Swaping in a 9 inch
I've finally got ahold of a 9 inch rear for my 57 chev truck project.
But now I need to make some adjustments. So 2 questions:
1)The original rearend is about 62" flange to flange while the new one is 65" roughly. Should I have it narrowed to the original dimension or something different? Or leave it alone?
2) The new rear has 2:75 gears. What do you guys think is optimum for weekend use to and from shows with some freeway driving? It's a 500 hp 454 mated to a T400 transmission.
