Default Stock height leaf springs / Street ride quality

Please read.. there's a reward at the end.

Quick background: I started my 1975 2WD Scout II project almost 10 years ago. I rescued it from the woods after sitting for 8 years. Took it completely apart & put it back together. Problem was, once finished, it drove all kinds of horrible... like, scary horrible. I have had a few early 70's Broncos & a CJ7... they drove great on the street... but not this guy. Anways, I quickly ran out of funds, so there it sat. Now, I want to "finish" this project... hopefully you guys can help. The picture is the "before & after" of when I found it & after the "resto-mod"...

Stuff done: Replaced 196 4 cyl / 3 speed with a 1996 Chevy Vortec V8 / 4L60E automatic combo & in-tank fuel pump. Added a 1" body lift w/ all new body bushings. Added brake booster. Replaced all spring bushings, shocks, & added power steering box w/ a Borgeson steering joint.

From what all I have read (and I have spent hours & hours reading all the suspension posts) if I'm running 30-31" tires, I need caster shims & possibly a reverse shackle kit. I'm wanting a street cruiser b/c it IS a 2WD, afterall.

Springy stuff: My rear springs are flat as flat can be... my fronts don't flex at all. I think I put regular Monroe shocks on it. I plan to run a Terra top I found instead of the full top I have & the Chevy motor setup is approx 100 lbs lighter than the 196... So the way I figure it, I'm losing approx. 100 lbs on each end from stock.

Also, my front axle is "bowed" so that it looks like a U shape. From center, it rises maybe 3/16 to 1/4 from perch to perch. I read that alignment shops used to do this to correct camber. I found & bought an almost straight one, but not sure if I need to use it... but when I roll the axle via shims, I wonder if this will throw everything off.

I looked for a long time (years ago) for stock height springs... I see that you guys offer them. Since you guys bit the bullet & had some made, I want to get all the items needed from you to get my rig running down the road properly... Last year, I moved from rural Alabama to pretty much downtown Atlanta, so I need my truck to be "right" to fight this diseased traffic...

So here are my questions: Will your stock springs do the trick for my setup? What degree shims? Reverse shackle needed? Use the straighter axle tube I found? Are the rubber spring bushings really that much better for street use? Should I lose the 1" body lift? Any extra input?

Reward: If anyone actually read all of this & can reply, then I offer a sincere thank you & offer up an interweb handshake. That's the best I can do here... but if you were sitting next to me, I'd buy you a beer or 6.

Default Re: Stock height leaf springs / Street ride quality

I would take it in to an alignment shop and have them tell you where everything is at, camber, caster, toe before doing anything else. They can adjust the toe if it is off. All kinds of horrible is not very descriptive, but most likely problem is caster, especially if "death wobble" is the "all kinds of horrible". Don't know about the 2W drives, but 4s had 0 caster. I'd try sticking a couple of 2 degree shims in from the front and see how that works out. Body lift shouldn't affect anything, but longer shackles definitely would.
