" I know from experience that the 2.87 uses the same carrier. The small
" carrier starts at 2.73 (nothing available for the AMC 20 between 2.73

" 2.56 IIRC. I believe that was the highest gear available for the AMC 20.

true afaik.

good but doesn't include hummers.

" The AMC 15 is a whole 'nother can of worms! It's close to the same as
" far as factory gears. I believe the common or "3 series" carrier runs
" from 2.56-4.10, with a special carrier for the rather rare 2.53 gears
" used a couple years, and another for steeper than 4.10/4.11 -- from the
" factory. Aftermarket companies have 4.56 and 4.88 gears that fit the
" factory carriers. At least I could find no evidence that another carrier
" was needed for aftermarket lower than 4.10 gears.

iirc there was never a 2.56 for the amc15.  for tall gears there were
not only the 2.53, but also 2.37, 2.35, and 2.21.  the 2.37 had its
own housing as well as carrier.

then there's the dana 35, the amc15's reincarnation...  and according
to http://jeephorizons.com/tech/pdf/dana_light_axle_manual.pdf pp3
there's even a 'super 35'!  hmmm - the new model designations look a
lot like ring gear diameters in mm.
