It appears the king pin bolts are uniform, I got the same readings on both sides, and in a couple different positions. The most accurate would be off the pinion flange as that angle would change in proportion to the angle added at the spring perch, and there could be some variation between bolt heads on other vehicles, this one just happened to be all uniform. Yes, this was off the old blue one that WAS in my garage, the body took it's final trip to the scrap yard today, and I brought the rolling frame back home as a spare and a test bed for the F'glass bodies when we pop the first one. The rear pinion angle measured at the flange is 10* /- 1 *. If running a CV shaft in the rear, then you need to kick it up so it points right at the T-Case flange. I think I am going to blast this frame and high gloss it to roll under my hard top winter project. I am going to pull all the parts off the white soft top one that is in the driveway to go on the bare hardtop tub I have.
