82-89 and 90 - 92 housing difference?
Ok, I bought a 91 transam rear and I intended to build it with posi, gears, and convert to disks then swap out the one currently in the car. While I was taking the backing plates off I broke all four small bolts off in the housing and I need them out to drill the holes for my disk backing plates. The housing is really rusty and pitted so I was wondering if it would be ok to toss the 28 spline axles and posi into the 83 housing. I know they have visually different center housings, is there a difference in strength?

There were many changes to the housing from 82-92 but nothing that prevents you from swapping parts around in them. You just need to swap the 28 spline axles and carrier (posi) into the older diff.
