Looks perfect :metal: Do you plan on putting anything under the rear tubs or just bolt them down. idk if they came stock with anything around the outside/underside or not, but notice where the strips meet the tubs there's a space. Would allow for water to run thru, but idk is that normal? Your BB seats and console look real good! Like that two tone combo for them.

Re: Dave's 1970 GMC 402 Longhorn
 

Truck looks absolutely gorgeous!!!! GREAT work!!!

Re: Dave's 1970 GMC 402 Longhorn
 

I -should- have put in the seals I already had purchased, but since I didn't take them apart (body shop did) I didn't know they were there!

I wound up sealing mine with RTV but doing it as tidy as if it were my bathtub, and it turned out great. Hopefully it's flexible enough.

Re: Dave's 1970 GMC 402 Longhorn
 

Here's a shot of one of the mirrors installed. I opted to keep the big Sr mirrors but had them stripped and chromed to reduce their "visual mass".

Re: Dave's 1970 GMC 402 Longhorn
 

Here are the brake lines I fab'd up, since no one seems to offer a proper set for a 3/4 ton 1970.

Re: Dave's 1970 GMC 402 Longhorn
 

Here's my gap cap. How existing is a gas cap? Not very, but mine was used for 40 years and was rough, but I managed to polish it all out pretty nicely.

Re: Dave's 1970 GMC 402 Longhorn
 

Very nice!!

Re: Dave's 1970 GMC 402 Longhorn
 

I would be lost working with such much CLEAN!

Re: Dave's 1970 GMC 402 Longhorn
 

This is the best Longhorn I've seen.period..

Re: Dave's 1970 GMC 402 Longhorn
 

Very nice! Your mirrors and brake lines have turned out super!

Re: Dave's 1970 GMC 402 Longhorn
 

Thanks for the kind words folks! I'm into this about 2 years now, but there's light at the end of the tunnel. Like any project, the last 10% takes 30% or more of the time.

Re: Dave's 1970 GMC 402 Longhorn
 

Here's the center stack.

Re: Dave's 1970 GMC 402 Longhorn
 

Simply GORGEOUS truck!!!

Re: Dave's 1970 GMC 402 Longhorn
 

Got the carpet, tank carpet, and one seat in today!

Re: Dave's 1970 GMC 402 Longhorn
 

Also installed the fuel tank, filler neck grommet, and my nicely hand-polished original cap.

I wound up reusing the original grommet; the "NOS" replacement was significantly different. It was genuine GM but not made when the trucks were, it was a later service part.

I turned the grommet upside down since the top had been seeing the sun for 44 years (though it must have been garaged, since the rubber was actually in OK shape).

To 'restore' the grommet I used some "waterless car wash" spray I had on hand. Cleaned it to a nice bare rubber color, but still gray. So I used "Tire and Wheel Shine" stuff which gave it back the black appearance, at least for now. Not sure how long that will last.

Re: Dave's 1970 GMC 402 Longhorn
 

Looks good!

Re: Dave's 1970 GMC 402 Longhorn
 

I bet your truck was garaged and well taken cared for to some degree at some time. It's pretty rare to be able to use stuff like that on trucks here. Even your fuel cap, that is nuts. Good deal for you though!

Re: Dave's 1970 GMC 402 Longhorn
 

Shouldn't that nos cap have a nos sticker on it :sexy:

Re: Dave's 1970 GMC 402 Longhorn
 

Shouldn't your cab be the same color as the box? :-)

If I had $11.99 kicking around I could get this, it comes with the sticker.

Maybe I should run that one instead of my original for when some idiot eventually steals mine.

Re: Dave's 1970 GMC 402 Longhorn
 

That's funny :lol: It's all color, now.

http://ilsiciliano.net/truck/DSC05773.JPG

That gas cap you linked to, it says "manufactured to original factory specifications" which means the sticker is OE.
Not something I bought. Original, like my bench seat. :metal:
Also notice the one you linked to doesn't appear to say MADE IN USA like mine. ;)

Re: Dave's 1970 GMC 402 Longhorn
 

To anyone following along, that link is for a non-vented truck WITH a charcoal cannister. My truck is non-vented, no canister. I'd presume they have different variations to match the requirements of your year and style.

I think the C20 is different than the C10 even in some years (the HD trucks didn't get the cannisters until later, I believe).

Re: Dave's 1970 GMC 402 Longhorn
 

Oh, the cap was plenty rough, though the truck did indeed lead a sheltered life.

Here's part way through; I went down to 60 grit on stainless steel at high speed, so you can imagine the types of scratches I was dealing with.

In an unrelated matter, if anyone would like their gas cap converted to a billet-looking brushed stainless steel, I'll do them for $100 a shot :-)

Re: Dave's 1970 GMC 402 Longhorn
 

hahhahaha, the cap in that link says "Made in Mexico"! :lol:

Re: Dave's 1970 GMC 402 Longhorn
 

Man I have to say the truck is coming along beautifully!! I am really impressed.

Re: Dave's 1970 GMC 402 Longhorn
 

Been a while since I've updated. As anyone who's done an "every nut and bolt" restoration likely knows, the last 10% takes the longest. It's not like TV.

Anyhow, here's the brake booster I just got from BrakeBoosters.com

Having been set back quite a bit by a parts store replacement unit that had studs too short to hold the master and brackets, I was in a rush. To avoid shipping the core I elected to let him restore one he had on hand (we checked all the proper stamping codes and rods and so on first).

I think it looks great. While it should be black in a '70, I'm running 72 brakes (front discs), so it's correct for the brakes if not this year of truck. And the gold zinc or dichromate or whatever looks way prettier than black. I let the NCRS guys worry about that kind of stuff.

They apparently spend a lot of time polishing them. My parts store unit was really rough, pitted, and even [b]rusty[/u] right out of the box. This one is smooth because it first goes to a polishing company and then to a plater (unless he plates in-house, I forget now).

Anyway, I'm pleased with the results and here's a pic! The master cylinder lid is something I did and not them, so blame that one on me!

Re: Dave's 1970 GMC 402 Longhorn
 

Looks great! The details make the difference between a nice truck and an amazing truck!

Re: Dave's 1970 GMC 402 Longhorn
 

Wow, very nice! Who did all of your chrome?

Re: Dave's 1970 GMC 402 Longhorn
 

Very nice!

Re: Dave's 1970 GMC 402 Longhorn
 

Couple of new photos. Added three point retractable belts because I'm too good looking to risk my face on that wheel.

Re: Dave's 1970 GMC 402 Longhorn
 

BTW the belts are pretty much invisible when not in use. It's certainly not a style choice I'd make, but there are a lot of fatal head-on crashes on the non-divided highway I pretty much have to drive on.

No mods required except an additional hole through the seat brace under the floor, but that's well hidden. And I saved the little plugs for the shoulder belt bolt holes....

Re: Dave's 1970 GMC 402 Longhorn
 

Managed to get it driving far enough to take it outside for a photo... first time in 3 years almost!

Re: Dave's 1970 GMC 402 Longhorn
 

Very nice!

Always admired the people that have that much time, money, and love for fine classics.

Re: Dave's 1970 GMC 402 Longhorn
 

Wow looks great!! Will you be keeping those wheels on it or are you going with the wheels that came with the truck originally?

Re: Dave's 1970 GMC 402 Longhorn
 

I'm not just keeping them, I put them on intentionally. But if I show it somewhere that I think values originality, I have the original wheels. I'm just not a fan of the white-wheel-poverty-cap look.

Edit: Just FYI, these are 73-later hubcaps, not quite correct for the truck.

First Drive!
 

Yesterday I pretty much ran out of things to do. Some minor things like the radio speaker not working, but I couldn't bear to pull that glovebox again, so I did something else.

I drove it for the first time in 3 years.

Took it a mile or two up the road for gas, stopped once along the way to check things out. Might have a bit of brake drag on the back left, as the drum was warm to the touch, but not red hot or anything. The four-speed auto lens might be half a gear off, little adjustments like that.

I'm not stoked about having kept my somewhat loose converter in the 200-4R. I'm suspecting I will need to change that, as it doesn't creep at idle. Of course I only have it idling at 500 as well.

Oil pressure great, ammeter charges or maintains with every load on (100A alt), stayed 180F the whole day. Really no significant issues at all.

I'm pretty happy given it's probably 3000 pieces I took apart, restored or refinished or replaced, put them back together and drove it to the store without incident... and it's my first one.

Thanks for all of the help and encouragement along the way! This board has been an invaluable, if sometimes frustrating, resource for all kinds of questions that came up along the way. The community knowledge is a huge asset!

I also picked up my new Z06 Convertible last week (nice work if you can get it) so it happened to be in the background because I had to move it to get the truck out, but I left it in the photo because it's 45 years of GM in one pic!

Re: Dave's 1970 GMC 402 Longhorn
 

Congratulations Dave!

Re: Dave's 1970 GMC 402 Longhorn
 

Awesome Dave :metal::metal:...but now it's a used truck again :lol::lol:

Re: Dave's 1970 GMC 402 Longhorn
 

Nice- I like both of them. Did you pick the vette up at the factory?

Re: Dave's 1970 GMC 402 Longhorn
 

Tiny picture, but here are my NOS (still in the green paper wrappers) hubcaps. Don't ask. Ok, you asked: $1500 on eBay.

Lest you think I'm crazy, there were 29 other guys bidding right behind me! So I migh be crazy, but I'm in good company. Not many sets of these out there I imagine.

Re: Dave's 1970 GMC 402 Longhorn
 

Dang! That's sweet! Sure would like to have that kind of money! I would be "crazy" also!
