Question on 68-72 Olds type "O" Rear

[joe huestis]

Thanks for all your responses. Danny, we are going to move forward on this project a little at a time. Fred installed a line-loc and drag shocks this past weekend. The gears are next. We are seeing how much we need to do to run a tad below the E/Pure Stk. index without drastically altering this pristine all origional muscle car. Only 13K origional miles on odometer !
Bob, I am anxious to see this through, I believe car has potential. When Fred had it at Piedmont last weekend, I was amazed at the folks coming over to check his car out. They walked right past mine and didn't bother ! LOL !!
