Maybe some one can help me out. Our company has a old 86 gmc top kick with a 3208 cat, eaton 5 speed, and eaton rear. I cant read the tag on the trans and cant really find anything on the rear other than eaton stamped on it. Can anyone help me out on identifying these?
 
Kinda what I have come up with. I'll have try to inspect it some more when its not snowing and thundering here.
Thanks

you're best bet is to take the vin number and call a gm dealer that you trust on the parts side with an older guy still working there that might know a little somethign about the older medium duty trucks.
 
The tag is still on the Trans but has been painted over. And i thought the rear was a little big and over kill for the truck.

About the only good info on the rear end I'm coming up with is that it has a 17 ring gear. Not much more info on it. Or could be looking the wrong places. Any info would be greatly appreciated.

I can try to run those numbers off the axle while I am at work in my spare time, are you able to get a picture of the brake shoes though? preferably the ends where the rollers are sitting. But a pic of the whole shoe roller to roller please.

107495. If they are on the end of pinion shaft I'll have to take drive shaft off.
