ON all the stock front end cars I've done (4 different cars in the past 3 yrs).....the front torsion bar setting required tweaking....for the first few miles of driving. One side was low...leveled it out...the other side went low...leveled it out...the other side went low....you get the idea. I was measuriing the inside of the front fender wheel wells each time. My concern was too get it "looking" level. Once leveled, I checked the amount of adjuster sticking out AND measured the distance between the LCA and frame. They always came up the same on both sides. I liked using the fender edge, 'cause I could make the measurement quickly with in 1/16" from side to side. Now I know some will say you can't count on the fenders lining up, with the frame even. Yeah..I know. but optically.....the fender level is what you see.
On the rear...I've been lucky. All have sat level. 2 had rebuilt OEM leafs, 1 JC Whitneys....1 Mop. Perf.
Someday....alterkation. I'm thinking more and more that the chally is the Keeper...if so...that may get the alterkation. I'm going to decide this spring on which way to go. I've got 2 complete V8 Ebody setups (OEM T bar). I could probably sell them off and get a good chunk set aside for the alterkation!
