73 interchangeable parts years and Chevy mode list?

[markrazz]

is there a thread or list somewhere of the exact interchangeable body parts and Chevy models through the years that are interchangeable with a 73?
Is it 73-80 or are there more years still that interchangeablebody parts?
If I was searthing for body panels etc what other Chevy vehicles could I use donar parts from?

Thanks

Other than using an LMC catalog or similar to look at the year ranges of parts there's no published interchange list that I know of.

The front clip (hood, fenders, etc) will interchange 73-80 but there are cosmetic differences in the grile & grille trim through the years.

The door shells will interchange throughout all years however there are trim differences. 73-75 doors do not have an upper window frame, 76+ doors will work but you'll need to cut the upper frame off and do some semi minor mods to make them work (all related to the cut).

The body tubs change through the years. There are obvious changes like the full top vs half top ('76+) and things like the floor pans, then less obvious like the exposed gas cap vs hidden with a door ('78ish). The 73-75 tubs have reinforced rockers to resist tub flex, later years do not but could be strengthened.

Trim is mostly a 73-80 vs 81+ thing, there are still cosmetic changes within those ranges too.

It gets really complicated as I'm sure you've seen. Your best bet to post a short list of immediate projects and folks can tell you what interchanges, once completed do it again with the next list of parts. When asking for this info you might also state how far you're willing to go with respect to modifications to make stuff work as this can narrow / broaden your window of interchangeability.

Thanks for the great info
I just want to swap out the rust for new and it’s all rust lol
This will be a driver so not too concerned with trying to keep it original as long as parts swap directly I’m fine with the small changes etc.
