Ring and pinion interchange?
 

Hi All,
We have a 72 Courier (re-branded Mazda) with the 10-hole flange center section diff. We would like to put the (I think) 86-88 TII or TT center section in it. Is there any reason the ring and pinion from a B2600i (3.27:1 ratio) or something similar would not mount up on that center section and clearance out correctly? As an example, we dropped a LSD unit with 4.56 gears into our 3/4 ton with 3.50's and had to machine the LSD unit to get it to set up right because of different back spacing.

Thanks, Ron

Just had one of those OOPs!! kind of moments, and realized the R&P won't interchange, thanks anyway.
