ok so i got the 68 outta cold storage, free from the snow around it.
after taking it for a quick spin last eve,
i think i need to get the camber adjusted.
noticed wear on outside edge of tires
it tracks str8, had it running 90+ for a few miles.
seems good other than a lil bouncy

i'm running 245/60R15 bfg radial t/a front tires, 2.5" drop spindles w/ about 1 coil cut from stock spring. air bag inside coil, 5psi, a lil soft so probably goin back to 8 psi.
what's everybody running for spirited road driving?
this in not just a str8line truck

try -.5 deg. camber and get as much positive caster that you can to help high speed stability. and an 1/8 inch toe in. make sure you set the ride height where you are going to drive it or your specs will change and cause excessive tire wear and poor handling.

I agree with Smashedfoot. My 69 has drop spindles on the front, and when I aligned it I was looking for 0 degrees camber, and went there first. After getting that ( or close ) I fiddled with trying to get as much positive caster as I could. What you will find is that you will run out of bolt on on both rear bolts. In a perfect world the right side should be a bit higher than the left IE: right side caster 1.5 degrees + on the left side 1 degree + this will help the truck track straight. all roads have a crown to them, and the spread in the caster will compensate for this.
