You might need to add a bit more info on what you are looking for. Are you looking for a stock 1/2 ton Dana 44 or a 3/4 or 1 ton and what gearing do you need?

1972 blazer rear end from a 4x4

Is the gear ratio wrong? Or is it 5 lug and not 6? Maybe it's an earlier, narrower rear? What's the problem you are trying to solve? If you think the front is wider than the rear and you want to even them up, that's not going to do it....

The rear being replaced has bad pinion bearing for sure, and most likely , bad carrier bearing, would like to replace with leaf spring housing if possible , prev owner installed a truck rear at some time .not sure about width of current rear but will check.now has 6 lug truck.

The 1/2 ton Blazer and PU should all be 6 lug and fairly easy to find. You'll want to make sure you are getting the same gear ratio as the front end or you won't be able to use 4wd.

[Mike C]

Do you just want a replacement with same gear ratio? Still not sure what your goal is.

Why do you care if it is a pickup rear? How can you tell it's a pickup rear? Is it a coil spring setup? The 4x4 should be the same width with same spring spacing, and all 4x4 were leaf.

The 2x4 leaf trucks are 42.5" spring centers and the 4x4 are 40.5". Axle housings from 67-69 are narrower with 70-72 wider overall, there may be some mismatch in 70 as they were using old inventory.

If it were my truck and I needed to redo the rear, I'd get a 6 lug semi-float 14 bolt from an '88-'96 truck. I've had 3 different OEM rears in my truck and built at least 3 more. They all gave up one way or the other. In the mid '80's that was not an option for me so I did 12 bolts. Would have been WAY ahead of the game if I had converted to 8 lug axles back when.
