www.chevsofthe40s.com has most anything your going to need, even a MII setup which may be easier/ better than a Camero/ Nova clip. I know that '53-'54 Chevy's are chop'd a lot, but the chop is very involved and complicated.

also http://www.nationalchevyassoc.com/home.html this place has a lot of '53-'54 Chevy stuff.
