Looking for someone to school me on Cuda doors. I am working on a 70 car. What years were the same or what years would interchange with only small modifications. Whats is the best way to tell the different years apart from one another?

Thanks
Dan

I beleive there were two different window regulators used but most other parts interchange.

1970 the outer window sweeps clip onto the door frame.

71-74 the sweeps use screws to attach them

there are other difference but this is the biggie one

window regulators themselves changed almost year to year per the OE pt number

Thanks, that's what I needed to know. Looks like I better find a set of 70 doors.
