I'm tech challenged and have trouble doing pictures. I'll see if I can get a friend to help me. The holes lined up with the radiator support perfectly. Once I got the hoses off the old radiator, the whole job took less than a half hour.
if you could that would be great how much space do you think you have between the fan and radiator are you running the stock fan with a spacer?
Ive have seen and installed three of these champion radiators one in a 64 dart (cc63dt) 66 dart (CC6566 pretty much same radiator just different wider mounting brackets do too the bigger opening in the core support) and a 64 Valiant (CC63dt).
With the stock mounting hole the radiator sat way too high and the hood would hit the radiator cap we had to drill a higher hole to lower the radiator, im wondering how yours fit with out any mods?
