I have a a 1951 pickup with a rearend of 56 inches flange to flange. I wondering which types of vehicle rearends with around a 3.5:1 gear ratio would work in my truck. I placing a TH350 turbo transmission in the truck.

It's a bit wide, but it works for now (actually for the past 8+ years).
Another quality post.

Grab a tape measure, there are lot's of options. Spring perches will most likely need to be changed, no matter what you decide to use.
My brother in-law "27Capitol" has a '51 also, and he chose one from a Pontiac Trans Am (I think it's a '78) positraction unit.

I really appreciate it.
| | | | | Joined: Jan 1970 Posts: 365 Shop Shark | | Shop Shark Joined: Jan 1970 Posts: 365 | I used a 9" Ford rear end from a 77 Lincoln Mark V. It has disc brakes. It came with 3.00:1 gears but I swapped punkins out of my 66 Ford pickup which had 3.50:1 gears. This was an improvement for both the Ford and Chevy pickups, as the Chevy has a 89mm tranny with .73 overdrive. | | | | | Joined: Nov 2008 Posts: 355 Shop Shark | | Shop Shark Joined: Nov 2008 Posts: 355 | ackk NOOO not a ford in a chevy :P now its .... frankenstien
