I have a 76 280 and need a door what years will fit. just 75 and 76 or can i go older. or should i just fix the rusty old door i have.

I've kind of got the same situation. With regards to fixing my door myself, I don't weld any more, but I'm seeing more and more info on Bonding panels instead of welding.

Here is an interesting link I just came upon on adhereing lower door skin with bonding.

I might end up trying something like this. Gary

74-76 doors should work for you.
