Dropmember in a 69 C10 - Page 18 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Thanks for the link,your project is coming along very nicely.I want a blazer.

PBFAB.COM · 01-09-2008, 03:17 PM

Thanks for the help Gringo!

Because the rack and pinion is attached directly to the Dropmember, there is no longer any large amount of stress from the steering components on the frame in front of the notch... It could be boxed for looks and "overkill". I did not see any cause to design/build the notch differently.

Dan-

I don't have any good pics of the triple-single-u-joint set-up. I set-up Kyle's blazer this way, but failed to take any good pics. It was originally set-up with a double on the column and a single at the rack... if you search the Blazer forum for Dropmember his build comes up. There are a couple of bad pics on pages 5 & 6 if i recall.

I thank you for the pics and expanation. I realize the rack position dont allow for much flex like a steering box would,was just looking for a few clearer pics of the actual rack notch.
You guys are Porterbuilt do awesome work,too bad I dont live closer.
I am sometimes a little more over cautious I guess,when I built my c-notch for the back of my 72 I went ahead and partially boxed that rear portion of the frame.....I guess for aesthetics mainly.

PBFAB.COM · 01-09-2008, 05:42 PM

Nothing wrong with over engineering or over building something!

It definitely never hurts to box any part of the chassis... especially after cutting it!

Slammed1, I have a dropmember in my 72 blazer. You are more than welcome to come by and check it out. Im in pocola

1LoC10 · 01-31-2008, 05:40 AM

66chevy PROSTREET · 01-22-2009, 11:35 PM

Yep. No gettin' 'round it...

66chevy PROSTREET · 01-22-2009, 11:55 PM

with the basic kit, you have to find your own rack, or is that standard?

Basic kit does NOT include the rack and pinion. Summit racing is running a good deal on a quality unit:

thankyou

You can also pick one up from your local parts house for about $100- core charge included. They are rebuilt and painted black, but warrantied and work well if you're not looking for bling...

Which truck was that off of by chance? Been a long time since you said that, but figured I'd ask

Nevermind, just looked on the application on summit's site for the rack Nate posted. 79-93 mustang unit, makes sense.

BFRO$TY · 09-01-2009, 10:56 PM

so me and the old man have finally came to the conclusion that we are gettin one, where could i go to figure out how much it'd cost to get one of these to my front door?

Just e-mail me your number and I will give you a call. Or you can feel free to contact me at 480-326-6303.

NPilot1975 · 09-14-2009, 10:30 AM

Nate,

Finally got the dropmember in for mock up. I think I may have put the reinforcing plates in backwards or upside down? One of the bolts on each bag plate ends up behind one of the vertical supports, but otherwise went in fairly easily. It looks so much better than the stock mess.

My question is at what height do I put the transmission crossmember? Does the supplied crossmember go at the bottom of the frame?

Thanx,
Jamison

The inner supports will only line-up one way. The radiused part of the inner frame supports will face the engine. Go ahead and e-mail me some pics so I can get a better idea of where you're at!

On the transmission x-member, I normally bolt it to the tranny, and then adjust the transmission to it's desired height and angle, and then mark/drill the mounting holes through the side of the frame. Do this with the cab in place to ensure proper clearance. If it's just a rolling chassis with no cab, let the x-member set on the bottom of the rails until you get the cab in place.

NPilot1975 · 09-14-2009, 12:46 PM

I will try to get some pix. It is not a big deal because it is coming back apart before final assembly. I just wanted to check fit with the LS in the frame and get an idea where the trans crossmember was going to end up to have a thicker boxing plate where it is going to be. I am going to modify your trans crossmember or a early classics one I have.

The inner supports are radiused inward. I just notice the the "open" end in some of the pix in this thread face forward, but I have mine towards the rear (if you think of the over all support as a U layed on its side.)

NPilot1975 · 09-14-2009, 12:52 PM

One last thing I was thinking about. I am planning on using a 2 piece driveshaft. I have read all the threads on how to do it and am still not 100%. Looking at the engine it is going to have a downward slope, can I run the front driveshaft parallel to the frame back to the center crossmember then let the drop in the rear allow the rear driveshaft to angle up.

I know if you are using a single driveshaft you want like 3 degree down eng and 3 degree up rearend for proper u-joint lubrication. Any help would be appreciated.

NPilot1975 · 09-29-2009, 08:52 PM

Finally took a few photos. First is looking from behind and second two are looking from in front of the dropmember.

dan468 · 11-02-2009, 11:07 AM

More sweet pictures, looks even better with powder

Tagg33 · 11-02-2009, 11:50 PM

Very nice, I'm just getting my DM mocked up. Paint or powder for mine is next. It's great to see your progress.

dan468 · 11-15-2009, 03:24 PM

Can Nathan or anyone else with the drop member please supply picture of the upper shock mounts bolted into place?

Thanks!!
Dan
