8 3/4 and 8 1/4 rear ends

I would think the rears that Ma put in her cars were adequate for the horse power or they would have had more warranty work than was feasable. Now when you start putting a great deal of hopped up motor in the cars then you need a hopped up rear end. I do like the 8.75 better myself but i do have some 8.25's. Have redone both type and once you do em they neither one aren't bad to do. Kinda fun actually. Gives one a sence of accomplishment. You do need some real tools though.
