what is correct radiator?

part# 3673905 1973 22'inch 225 AUTO A/C

fan shroud? if i had to guess yes. if not take a 22' 318 auto radiator and use the mounting brackets and shroud from it. the 318 car will have a shroud. this is of course if you are trying to put it back to a slant , or if you just need a shroud for the one you have now....
