8 3/4 adjuster far in

All that said
it is NOT uncommon for the rear ends in our A-bodies to not be centered in the car. Sometimes the rear is shifted, and sometimes the body is shifted. Neither of these affect the car, other than the thrust-angle, which for a streeter is no big deal. I swapped my adjuster axle from one side of the car to the other to get it closer, just because I wanted to fit 325/50-15s in the stock 68 Barracuda tubs.
