A body big bolt pattern differential ?
 

Hi people, I have a vg valiant regal, running a hot 318 ,Fully worked 302 head's, hyd roller cam, ld4b manafold and 650 vac sec carb . Goes great but need to upgrade the differential, got small bolt pattern 7 1/4 diff - what's around in the junk yards over there to fit A body with the bigger Ford type studd pattern and 1/2 inch wheel studds ?
any advice would be great
cheers

You would be looking for a 8 1/4 from a 73 to 76 diskbrake car. But they are not the strongest either.

Hey cool thanks for your reply, if this is not a great upgrade what would you recommend that's readily available from junk yards ?
Thanks for any advice.

Money no object ? anything can be made to work.. Direct fit ?? Big question ??? Maybe take some measurement from a early 60's mustang / Falcon Or a B body 8 3/4 and have it shortened with custom axles. A body 8 3/4 are out there but hard to find and expensive
