i just got a 68 roadrunner with 456's and would like to change to 355 or 370 rears anyone want to trade?

 

I am sure there will be takers, but a bit more info is needed... 8 3/4" rear? or which rear-end are you working on?

 

What rear?

 

i think its a 8 3/4 dana with 456 gears I'll let you know for sure i have other more important issues that need to be fixed first my tranny is slipping in drive so i need to fix that first before starting on the rear it was raced and converted back to street and i want to change the gears

 

i finally got my tranny rebuilt and converted it back to a fuully automatic valce body but now it misses terriblly and the fuel pump quits after about 5 miles or so i let it sit for a few minutes and it starts again, relay? it ran fine when i towed it to the shop any suggestions? i also have this reverse manual valve body if anyone is itnterested in it the guy said its a good one

 

For the fuel problem Check all of the hoses at the tank.. look for cracked hoses... . 68 RR NO relay unless it is modified with an electric pump

 

there is a 8 3/4 " diff will a removable carrier from the front OR
there is a 9 3/4 Dana 60 with a removable rear cover
1 or the other !

 

it's an electric fuel pump i just didn't get a chance to check it yet
