Howdy all. New guy here. Just picked up a 1966 Galaxie 500 Hardtop. Been eyeballing it for a while then finally picked it up. But I do have a couple of questions about it.

I have been looking for some kind of parts interchange manual but havent been able to find one. I've searched the threads and found a few things bout it but not enough. Looking for what brands/years will interchange but mainly for trunk/floor pans.

Are the Crites 429 mounts worth the money? The car came with a 302 but he threw in the 429 with it.

Also I picked up a 69 disc brake setup will this fit? This is from the original car that came with the 429. So I guess I will need to take it all springs, sway bar ball joints etc.

Thanks for everything in advance
