I can't remember if I posted this quesion before, but humour me.
I'm installing a front crossmember and spindles from a '84 Chevy into my '68. I'll need a new rear end so that I've got 5 bolt rims all around. My goal is to run a 400 SB with 425 HP with a 700R4 behind it. Which rear end would be a good swap-in? ![]()

Are you asking for strength or ease of swap? You will blow the 700r4 long before you waste any truck rear end.

They are very rare but I once parted out a 69 longbed 1/2 ton. With a Dana 60. It had non-full floating axles and it was a posi. That is the only one I have ever seen. One of the axles was bent at the flange because the truck had rolled. Moser made me another one. Has any other members ever run into one of these rearends? It also had the provision for the panhard bar cast into the housing. Used it on a 69 GMC shortfleet with a 396 and a 700R4. That was one beefy differential.

I think a 12-bolt truck rear would work fine...i have heard they are as strong stock as a Ford 9". Should bolt right in with the correct conversion U joint too

Couldn't you just swap 5 lug axles into it?

Just get a 5 lug 71/72 rear.
Bolts in, no fabbing, and you know it'll fit. |
