Would anyone know if the gears for a rear window regulator are interchangeable.
My 1968 barracudas left side rear window regulator are chewed up bad, so I was curious if I could just replace the gear part itself, with say rear window from a 4 door dart?
 
There are 2 gears. The small bearing like part where the winder handle goes is not exactly interchangeable but internal parts from a late model can be used to renew the original. I did this to my 67 driver door regulator using parts from a 75 model 4 door rear window regulator. If the larger half moon shaped gear is worn out, I honestly dont know how much interchange can happen there. Have you looked at how that part is attached to the regulator? It wouldn't be easy task. Even fastback and notchback B'cuda have the winder handle in different locations. I dont know if that means their large gear is different.
In the end, It might be best to just make a parts wanted thread. Rear window regulators never saw nearly as much wear as drivers door regulators. Rear window assemblies do have some plastic rollers and stuff in them and some owners would just fight/overpower rather than repair. I'll assume that is what happened to yours. Plastic parts failed, then metal parts eventually failed also. A good used regulator is out there. You may still need to hit up RT Specialties for the rollers. @barracudakid

Yep it's the big half moon type regulator. All the plastic seems to be good. I'll take a better look when I get home from work. Looks like mine got moisture on it and rusted. That and someone cranking on it while rusty maybe, idk. I'll give everything a good look over once I'm back home.
Thanks
 
Probably the same. I don't think Mopar has changed the gear ratio/mesh since the 30's. A buddy bolted a power window motor from a Cordoba into his 38 Dodge sedan. Like it was made for it.

Well that's encouraging, I know of someone who has a 74 4 door dart. Maybe I'll get lucky
 
Found a 1966 barracuda, anyone know if this rear window regulator might work in a 1968 fastback? It'll be a heck of an adventure getting to it. It's a story in itself.
