Gm anything in it. I am more into the flathead era and it is very common to see a Delco alternator in one. I put a Mopar setup in mine. Don't even get me started on a SBC/LS swap.

Not a fan of rockers on the ground or stupid oversized rims, on any era vehicle. Some lowering is good, but wow do some take it to the extreme.

An MII suspension on anything, a craptastic suspension that was originally used to replace even more craptastic solid axle, leaf sprung 30's era suspensions and once you replace everything stock with aftermarket it works, for values of work.

A four link on anything. There are way better suspensions for as much work.

A 9 inch rear on anything not a Ford.
