Wiper motor swap

Here are some photos of what I have. The problem with the "67 motor is it also sat out in the rain here in Washington, and the gear box appears to have some pin holes. After looking at the photos of your wiper motor mine maybe a Prestolite. Nice work by the way. My linkage and pivots are in great shape and if I use the 2822272 arm and the offset bushing do you think it will work? My understanding is the change of the motor and arm took place mid-year in '68.
