1986 GMC C3500 Rear Power Window Regulator

[cjlloyd81]

I'm at a brick wall here. I've located/ordered/have motors for all four windows, and window regulators for the front doors. Orielly's, AutoZone, NAPA, Classic Indusries, JC Whitney, LMC Truck... all are making me think I"m crazy because no one lists or can find regulators for the rear windows. The ones for the front in every system/catalog specifically state Front Driver, or Front Passenger.

Short of pulling them out (cause thats alot of fun) and comparing to the front's... Can anyone tell me if they are the same front/rear?

1986 GMC C3500 4 door long bed dually. wings on the front window, and inop sectional glass on the rear.
