eaton rear reliability

[61K10]

the eaton 32/33 was in 1955-62 1/2 ton tks. only one ring & pinion available 3.38 the 3.90 is not made any more (sadly) the bearings/spider gears/seal are the same as 1955-64 car. I am putting new bearings in one i just bought. hope it's quiet. Might take my org one and install the 3.38's but being 4wd that screws my ft axle up as it has 3.92's and the closest to 3.38 is 3.31 for the dana 44 which would be pushing it bunch. could run different tire sizes?? just trying to stay original.

now a hot-rod type tk i would go 12B or ford 9"
