This is the first time I have even seen one. But wondering what aplications they came in. The input seal is toast on the one I have sitting here. Here is the model number on the tag if that helps any T 221 n 7
 
The stomper came with one stock. SM420 and a rockwell married combo.

1967 3/4 ton 4X4 chevrolet No AC. Should come up for parts.:awesomework:
 
They came married to SM420s and SM465s for a few years (67-69?)


I think 60-66 K10s and K20s used a divorced T221.


Pretty tough unit from what I understand - used in trucks up to 2.5-T. Similar gear ratio to an NP205. Seals and gaskets should be available. Replacement hard parts are virtually non-existant. IIRC, there is a bronze bushing on either the input or output that eventually wears out and there is no replacement.

Never seen one, but I understand GM K10s and K20s had them from 55-59 or so. They were replaced by the T221 in 1960.
