I'm building a 65 Beaumont and am looking for a 12 bolt rear diff. Can anyone tell me what other cars have a diff that will fit or point me in the direction of one for sale.
65-67 Chevelle or Beaumont is all that fits. If you find a 67 rearend, you have to use 67 springs with it. The bottom part of the spring is different than 64-66 where it mounts.
Tough one to find, and lots of $$$

And I should add, the 67-69 Camaro 12 bolt is the same size but it's made for leaf springs, so that doesn't do you much good. Besides, it's worth even more than a Chevelle 12 bolt, and likely even harder to find.

The BOP was a tad weak. I sheared all 10 bolts on the carrier of my 65 GTO. Pulled away from an intersection, took second gear, and nothing. Stopped the car and looked underneath. The drive shaft was spinning. It was a weird sight.
I know some people run the 68+ 12 bolts in '66 and '67's even though they're an inch wider. Will they fit in the '64-65's?
I'll be back in town tomorrow night untill Monday if all goes well, and with any luck I'll be at Millars drooling over my motor. I'm located outside of Thornhill and the coffee is always on.
The way it's working out now, it doesn't look like I'd have more than about 15 minutes if you happened to be in Winkler around 9:00. Oh well, I'll be back there again sometime and with more time to spare.
The parts manager at Janzen's is a friend of mine, and we now happen to have another common interest in cars, G8's.

Nice my garage was full of Janzen cars thanks to Kurt over there lol. I'm not home a lot which is why this car will take forever but someday we will hook up. Your from Morris area? I pass through there on the way to the office quite often.
Kurt is in sales and he goes through cars so fast I have no Idea what he has, I used to play hockey with Marcel (if that's what you want to call it). I am going Thursday to pick one up, it's still in the car - 67, 4.11, 12 bolt should do the trick we are going to use a 496 stroker to supply the power
So make sure that you order 67 rear springs when you put that diff in your car. The lower mount for the spring on the 67 diff won't work with 65 springs.
