Probably several hundred times. The old standard is Specialty Power Windows but if your handy with tools Speedway has one for 150 bucks. Others like Bob's have direct fit for around $400. Before they offered kits we used units from 1970's Cadillac which took quite a bit of fabbing. One of these in a 1951 GMC is still working after 41 years.
Thanks for the reply. Both doors have all new guts. New glass regulators wing vents window channel anti rattle rubber and new Felt on the window garnish molding. Each side rolls down smoothly..gravity. rolling up they are stiff.. need some assistance. Yes an old Cadillac window motor would pull an engine. Maybe fight with it till the felt/rubber gets broke in
