In Need Of Some 8 3/4 Technical Info

Daredevil,
Thanks for the offer Ireally appreciate this group and their willingness to help.
Johnny, you need to read all the posts in a thread.
Charger,
your responce is the most interesting, I will have to do a little figuring and see if shorter than 51.4" ( stock A body length) gives me an advantage. Im building this thing for road racing and as is it will take a very large tire since I minitubbed it.
Andrew

What ?
I read the threads that counted.
Don sold you a rear end he said "would fit",that means an A-body rear.
He didnt say would fit after cutting,fabbing ect. It doesnt matter if it was $100.00 or $500.00 Don misrepresented what he sold you.
Andrew,you need to know what your looking for.
