Thanks everyone
After some back and forth with Auburn I do have the correct/available carrier. There is the split in carriers for higher gears but that one is actually wider at the ring gear seat to bearing seat dimensions.
I put in a narrower race 25520 I believe which is compatible with the bearing. With the pinion in this did allow the gears to mesh. It also makes some room side to side for shimming. It does however now rub on the side closest to the ring gear hitting the case a little bit and the cap quite a bit. Possibly it is this part of the case that's the issue. But even with the caps off there wasn't any play side to side.....??
Plan is to clearance it from the carrier with the grinder.
Auburn has been awesome to work with. Unfortunately they didn't have a good answer as to why the carrier isn't fitting easily. But that's life.
Overall this has been a major pain. If there is a setup for swapping the internals on an existing carrier that would appear to be a sure bet compared to the issues I've had.....and I'm sure I'm not finished yet
