The Stovebolt Site Forums The Shop Area Paint and Body Shop Doors 1936-46 truck window regulators??

I have four 1936 truck doors, 3 of the regulators are single arm and one is the dual arm.

Did the trucks use single arm, dual arm, or did different assembly plants use one or the other or both?

Also, are the car regulators interchangeable with trucks, or ??

Any insight is appreciated!

Thanks!
