I have a 70 1800E. When I bought it the pass. window crank handle was missing. I ordered one through the internet using the # from the one on the driver side. The problem is it won't fit, the hole in the handle is too small. (The Company won't respond to my email.) They both left and right sides look stock. But this care has a lot of history, and the mechanism may have been changed in a former life. Were there two different handles/mechanisms? Has anyone put power windows in an 1800? If I have to buy a new mechanism I may go with power windows.
