Dude Love The Build!!!! Wish I had Your Talent....... I'm Getting There...

Great job on the roof rack. It's awesome!

[greguw]

Hey Guys ... The Build is still alive and I have been picking at the truck , got the truck all stripped down and just finished epoxy primering the tailgate on saturday .
I have do some final blocking of areas on the panels and then get it prepped for the paint process .
I'm pretty impressed that the whole truck only took less than 1 quart of all metal and that was for small dents and the roof was the worst of it .
I also cleaned and prepped the insides of the door boxes and took Por-15 and a squeeze bottle and put a nice bead of the paint down the inside of the seam ... just enough to seal out any chance of rust down the road ... stuff worked great and just put enough but not close up the end drains in the doors .
I still have to decide on the flares , I have bought the best flares in my opinion ... Xenon flares are great compared to the crappy bushwacker junk .
I'm going to decide if I am going to cut in the area around the wells and the then mount the flares to be painted with them in place so there is no chance of them being stressed and paint peeling over time and I think that is going to be the best way .
I also just ordered the last of the finish parts , mostly seals and gaskets . I still have to track down some headliner material and my buddy owns a glass company so I will have him out for a few beers while we install at new windshield .

For the flares, just add a flex additive to the paint. cheap insurance IMO.

Sweet burb, that thing is massive!

[greguw]

I did get a chance to do some painting ... Looks ok for a go truck ... I have moved on to the jams , and start putting her back together . I'm going to hold off on the seats I just want to get the truck on the road and I need a break .
I have a commercial consew sewing machine forsale so I am trying to work a trade out for a shop to redue my seats and they get the machine , so will see how that goes .
Only parts I have to paint are the new Cowl induction hood and the cowl vent .
I had a few sliders and they seemed to sand out ... I'm going to let all the paint harden up for a few weeks then knock everything down and wheel it up then all my glass can go in .

[Dieselwrencher]

Greg, it looks sweet! Nice job!

[greguw]

Thanks Buddy , its not bad for a in the middle of the shop paint job ... Now I have to come up with a strip combination after I rub the truck ... I was looking at my 96 cummins and it has a dark aqua with a light aqua and that looks pretty good .

[y5mgisi]

Looks real nice! About the stripe, is it to separate the silver from the black? I think the light/dark aqua would look real good! Also, are you leaving the roof white?

[1985-GMC]

It looks pretty darn good man!

A white stripe would look good.

[thirdstreettito]

Separate the silver and black with a white pinstripe. It'll set it off!

I have a few questions:
Are you leaving the Cummins stock or doing power/reliability upgrades?
What is the minimum lift required for a Cummins?
Would 4.10 gearing be a Bad Idea?
Are there any cockpit clearance issues (radio area, drink holders) with the NV4500 HD?

I apologize if you answered these previously; multiple searches on this site are a bear due to re-search time requirements. I've converted my own '91 6.2 turbodiesel burb to a 2500 (hence the 4.10) but the 33" KM2s rub a little on turning. 20 year old suspension is crap anyways. When I replace springs though, I want it be lifted just enough to accommodate your drivetrain choice, because when the 6.2 goes it's Cummins Time.

Oh and your Suburbeast is coming along nicely!

[greguw]

For my build stock right now is just fine , I could see possibly fuel plate in the future but for a truck rolling on two different sizes 42 and 44"s with the 4.56 is just fine .
You can put a cummins in a stock truck just is a tight squeeze .
I have a 1" aluminum body for my clearance ... my suspension is custom Deaver springs and gives me a good 10" lift .
4:10 is a good ratio depends on your tire size and trans .
My NV4500 shifter is in the same location a stock shifter would come threw the floor on a factory truck .
All I can say is look thru my build and it was a ton of work ... I have basiclly worked on the truck just about every day for the past year and a half ... should be done for spring .

[flomulgator]

Greg,
thanks for the info on the clearances. I forgot all the trucks that came with manuals would have the same cockpit; good to hear it works fine. I know the Cummins likes to run lower than the 6.2 but you're right I could just keep putting on larger tires

Yeah the work you've put into this thing is next level. Yours will be a factory-new rig that never was but should have been.

[Greenlee]

Nice work!

Found some time to work on the rig ... got the body side bars on , painted the hood black and not sure how happy I am with that ... its on .
I just finished fabing up the grill . It was a GMC grill that I skinned the inside out and found some aluminum mesh ... think it looks like a ford raptor grill ...LOL
My buddy put the windshield in last week , I was able to track down a factory NOS gasket ... it was a pain in the butt .
I did side quarter windows and they were pretty tough plus I used sealant between the gasket and body to make sure no water gets in there .
Headline and some of the inside panels are all back in .
I put the 42's on the front when I was building my side steps ...
Just picking at it .... enjoy the snow .

[y5mgisi]

Despite the fact that the hood would look more appropriate silver, the truck still looks bad ass! Looks like a classy zombie killer!

[flomulgator]

That thing looks like a beast now!

[68Timber]

Beautiful!

[Dieselwrencher]

I don't know if I like the hood black either. But, the sub looks sweet for sure. Nice work on the grill and steps. If you painted the roof black, that hood would look so sweet black!

[thirdstreettito]

I just wish the bumper was moved up about 2" so there isn't a huge gap. Other than that its kinda sweet.
