I used Moser stuff in my car. I found a Diff. on the Moser sight that'll work with 33 spline axles but holy cow it's expensive. Here's a link. If it was my car I'd just go with the 31 spline axles and a C-clip elim. kit. There is a ton of options for the 31 spline axles. But if you have your heart set on 33s here's a link for the Moser Diff.

Damn thats expensive. Are 31 spline pretty strong in the long run?

Like mjr said. Stock 28s hold up fairly well. 31s are that much better.

Alright. So its looking like the 31 spline and detroit truetrac. With the torque I'll have and MT slicks, hopefully it can be a bulletproof rear end. Has anyone welded the tubes? Run a girdle?

I did both when I had the shop do my 8.8. I think you Gotta get the C-clip eliminators no matter what axle you do. It would suck to have a wheel come off.

Someplace years ago I saw a chart about how much torque a certain axle spline could hold.
31 spline was like about 15% stronger than a 28 spline. 33 was another similar amount over a 31 and so on......
