You are a man after my heart! I've done this sort of stuff for a long time,
a long time ago. But, there were no charts and obtaining parts from different
auto manufacturers to modify to fit the current project.
A real funny one was a Salesman came back and asked if I could install remote
control mirrors on a 1974 Fiat 124 Spider. After a quick thought I said "Yes"
and the sale went through. The mirrors came from an AMC dealership and the
New Car Owner loved them!
I applaud you to the MAX!
