My 74's passenger door is rusted on the bottom because the previous owner never bothered to repair a broken window seal. I'd like to replace it with a CORRECT rust free door using the original door panel & glass, but my questions are:

are all '70-'81 firebird doors interchangable? if not are only '70 to '76 doors the same?
any difference in door handles?
any difference in doors with & without power windows? (mine is equipped with power windows, can I install power in a door that came without)

Thanks, any help is greatly appreciated.

ALL 70-81 FIREBIRD doors will interchange & MOST internal parts will ALSO,but it's best to stick as close to your year as you can.

70-74 are basically the same & 75-81 are,as well.

75-81 inside door handles /mounting are different,but you CAN use your 74 door panel on them with the 75-81 escutcheon.

I believe 77 was the first year for the lighter/smaller outside door handle.
(the one that breaks all the time) Early & late will interchange)

Camaro doors are NOT interchangeable in those years,but inside components are.

The outside skins are different.
