the 2nd gen radiator is a little bit shorter height wise and a little bit wider the only thing ive seen so far different is the hoses might not line up straight. yes ive looked many places and only found oem so that might be my choice. just wanted to see if maybe someone on here has already put a 2nd gen rad. in a 1st. and getting one custom made would be pointless imo. i really only want it because its polished and will match my valve cover and headers. and it looks alot better then the oem black one i think
