Might be the time to finish the whole "Stock" thing. Put the factory wheels and redlines on, suspension parts are bent so the engine/trans and K will be coming back out the bottom again. It is still 4" bolt pattern
I have 3 wheels. I have the repro 893 pan and pickup! The car has been out there for 10.5 years now and maybe a re-model during this repair is a good idea.
I LOVE that idea. Go for it. You listed the parts you knew were toast. Fortunately, most of those parts are fairly easy to find. Hagarty advertises that they will search for hard-to-find parts for you. They will take good care of you.
