b-body

Came across this article, its from a while ago but still chock full of info: https://www.curbsideclassic.com/automotive-histories/the-gm-b-body-a-love-song-in-b-major/ Going to make some threads with stuff like this I find across the web, (full disclosure) just to get the thread/post count...

What other models can I get parts from that will work on my 75 Catalina 4-door? Been hell trying to find just basic stuff. How similar are the interior stuff to like the Olds and Buick?

aaaand go. Let's see if we can get a thread like the G-Body guys have built.
