OK, After reading thru you post (#1947), I have another approach I would like some advise on for my next build. I have a bunch of parts already just waiting to be used, so here is what I plan to put together. This would work for any '63-'72 truck since the suspensions are the same for those years...

Front:

Recessed the stock cross member up into the frame 1.5"
Porterbuilt Forward Lower arms (2013 versions)
Stock Upper Arms
Air Bags (could go to stock coil springs)
13" C4 Corvette Brakes on 2.5" drop spindles (from way2lo)
Upper Shock Mount relocated
Shocks - Would like to use Ridetech HQ series adjustable shocks, OR? (Don't have shocks yet)
1.25" Porterbuilt sway bar for the forward arms
No Limits Steering Rack Conversion Kit


Rear:

Modify rear rails (like you did with JT) to lower the rear
Air Bags (could go to 2"-4" lower coil springs)
Pan Hard bar - From mount is extended and has multiple holes for setting height, keep it long so that it mounts to Passenger side Trailing Arm at the end, Mount has 3 locations to help set height and keep the bar parallel at ride height.
Sway Bar - Don't have this yet so I am open to suggestions, Price might be a deciding factor.
Brakes: 12" C4 Corvette single piston, with drum in hat parking brake.

At this point, I am planning some sort of 18" or 20" wheel/tire combination, just not sure on tire sizing for the front or rear, any suggestions?

I fully understand that the performance of the suspension with be limited, but at this point so is my driving The truck will mostly be a fun driver that I can daily if I want to, but there will be an Autocross event for fun (Good Guys, local events, etc...) from time to time...

What other low cost changes would you recommend to maximize what I have to work with already? Taller Upper Ball Joints, etc...

Any advise would be great, I have a bunch of parts that I want to use and only spend money (with in reason) on what I don't have on hand to build my next truck.
Karl, this is really similar to the #4 version of the JT (bags on all 4). Our plan with the JT was to see how far we could take a 'stock' based chassis. Looks like your plan has better brakes. While 'vette stuff works great on 'vettes, remember the a C4 weighed in at 3100 wet, with 50/50 balance. The OE 12" brake from a 73-87 has more potential brake torque than the vette parts, but they are heavier. Just FYI. Would be a fun driver.

For the same money as other stock frame suspension mods on the market, I can get corrected geometry suspension using the Wide Ride IFS and Rear Fat Bar systems from No Limit.

While I'm saving up for this upgrade I have all of the basic knowledge of what can be expected from stock parts and cheap mods. Awesome, awesome thread!

THANK YOU!

Thanks Pat. I don't want to step on anyone's toes, or say that "this is the only way", but I also don't want to watch everybody learn the hard way, it's expensive and disappointing. Plan your build, build you plan.

So, would the taller upper ball joints give me any benefit? Looking thru my stash of parts, that is one item I will need to purchase. Stock or taller?

A taller ball joint will give you a little more camber gain under compression. If you are going to buy new uppers, you may as well get tall ones. Not too much more $$ for the benefit.

Re: Make it handle

Here's a simple question that may have already been addressed but I don't have time to read through 79 pgs of posts and the search didn't find anything. I have a 68 swb with coil rear springs. It sits unlevel so I think I need to replace the springs. What's the best replacement coil spring to get the best ride on a stock height truck? No racing or hauling, just driving. Thanks.

Re: Make it handle

Earlier, when talking about x braces, what about the 60-62 x-frame; would it be enough in its stock form to negate the need for boxing and x bracing?

The 60-61 OE SWB is one of the best GM ever made. It simply cost too much $$. Using one of these is a pretty good start, but the cab and core mounts are different 60-62, 63-66, 67-72, so it's not a direct swap.

So my first question is, Is it the front springs, or the rear springs? Park on level ground and then jack the front up until the tires are off the ground. Put jack stands under the front frame at even heights, so that the frame is level side-to-side on the stands. (isolating the rear). then check the rear spring heights. Then reverse the process and check the front spring heights.

Sorry, I should have gave more info.
My 65 is already on a 62 swb frame.
I was considering putting it back on a 63-66 frame, but after reading in these forums, I was wondering if I am further ahead just keeping my 65 on the 62 frame.
