Interesting... I've never tried hinging a resin hood, I just paint them and lay them on. I'm sure some plastic hinges could be glued to the resin hood w/ super glue, maybe? For Mopars, the AMT '68 Road Runner has a nice set of hinges, but they are the for an open use (i.e. the hood stays open with them installed). Those could be used if that is what you are going for. Functional ones, I don't know.
