Default Radiator Question

Hey Guys, I'm doing a frame off on a 1975 coupe. I had to replace the radiator support with a later style, Believe it is an 76L, Went to put in my original radiator last night and found the tank flanges are about an 1" longer and over lap the bottom mounts. The tank mount bottom flanges measure 26 1/2" center to center. I can't for the life of me find a direct replacement. Everything is 27 1/2". Any suggestions.

Thanks,
Ed

When you say you can't find a direct replacement do you mean the radiator?

The '76 late to '79 rads are 26 1/2" wide, '73 to '76 early are 27 1/2" wide. The two supports & alot of other things changed in late '76....

You either need the 75 support or the late 76 radiator.
