smoreau 658 #1 Posted April 15, 2011 I have 2 different 8 speed rear ends. One is in a 77 c120 and the other was purchased from flebay. It was in a c125. So here is my ? Is there any difference between them? I want one for a lawn mower in my 69 raider 12 and the other for a hard worker in my c120. The c120 will be plowing snow, hauling heavy loads, and will have ag tires on it with wheel weights. I'm getting ready to put these tractors together and want the strongest in the c120, but if they are the same I will leave the one thats already on the c120 where it is.

sorekiwi 761 #4 Posted April 15, 2011 The C-145 should have had a 103916 Uni-drive, the C-120 a 103907 Unidrive. Both were 1 1/8" axles and 8 pinions. Share this post Link to post Share on other sites
