Rear End

I was 25 when i "street raced" that was the late 80s early 90s.....yes its stupid as hell. we know that now that we are old.... point being if your going to spend money on a rear... why the heck would you spend money time and energy on a 8 1/4? ...like they say..do it right the 1st time. if 8 1/4's were so wonderful we wouldnt seek the 8 3/4. IMO not to metion ez center section gearing changes...maybe move the springs inboard while the rear is out.
