This is a pair of rear door window regulators from a 29 to 31 Chevrolet or other GM car of similar size.  Both are stuck and would require complete disassembly to make work (in my opinion). One has a bent arm. There are two sets that have  the handles and springs (these will go first). Another set has one spring and one broken handle and spring.  The lever arm is 10" centers and the gear has 4 3/4" centers. These are the same for several marques in the GM line up. I have several of these and others that all need work that I will be listing.  THE THING THEY ALL HAVE IN COMMON IS THAT THEY ARE STUCK.  The wood will be trimmed away before shipping.
