7 1/4 to 8 3/4 info needed

8 3/4 and you can swap gears Friday after work for races Saturday, and put the street gears back for your commute Sunday afternoon. What better excuse to get out to the garage with some friends with pizza and beers?

There is also the Ford 8.8. New axles for the small bolt pattern, and you call it good.

Just remember to wash up in the garage sink before you go in the house... ask me how I know. :(
