8N Pinion Change Problems

[Pace F20s]

I am (or was going to try)replacing the pinion in my 52 8N because of some damage on it. I have a good one and the ring gear doesn't look too bad, and I don't have a ring gear. When I tighten the left axle housing, the ring gear and pinion bind. Loosening the axle housing about the thickness of a thick gasket releases the binding. According to the book, there is no backlash adjustment. The book doesn't say anything about replacing them as a set. Anybody got any ideas? Thanks

b. Differential Assembly. The drive gear assembly (including the differential gear case) and the drive pinion are furnished only in matched sets, and, if either is damaged, both must be replaced.Replace the drive gear assembly if it has chipped or missing teeth,or loose or missing drive gear rivets.
