Ok so I picked up a 1979 cutlass
previous owner put in what I thought were 1980 doors with power windows
however after purchasing wrong motor and research I have a 1977 window motor and window track. It’s been a pain. Still window won’t go up or sometimes very slow. The rollers and track are old the center spring is missing which I think is suppose to help window go up

my question is are power window tracks interchangeable between years ?

I see the 1980s motors are way cheaper and I see some sets of motors and window tracks sold together as a combo

not sure however if you can put a new set of window regulators and motors on various years

any experience with this ?
