It's a 71 disc/drum. I got the spacers from one of the guys here on the board, they were made buy Burbank Suspention. There alluminum. Looking at the ball joints it looks like the upper is flat to the spindle, the lower look like I have about 3 degrees before I hit the inboard angle limit. It also looks like I may have to turn the sway bar upside down to get a better fit to the lower a-arm. I'm still working on getting a cam to get some pics, hey I'm not made out of money.
