I have a 1974 Dodge Dart Sport with a 225 Slant 6. I've tried both autozone and o'reilies autoparts stores and both only carry 2 types of radiators. The original radiator (which leaks like its going out of style) is 22" and the only two the afore mentioned auto parts stores carry is an 18" which I dont think will work (the holes line up and its fits but Its small) and a 22" which would fit but it has a bulge at the bottom below where the bottom hose hooks up.

This bulge is on the frame of the radiator, and for whatever reason Its not a manufacturer error, I've ordered two and both had it. Problem is, is that the bulge hits a metal plate near the bottom of the car (part of the frame that the radiator is bolted to) which in turn means I cant align the holes to bolt it in. Has anyone had this problem or does anyone know of another place I might look to get a radiator? I just need it to be 22" (as far as I'm aware anyways) and flat at the bottom.

 

Not a lot of followers here on the vintage cars I'm afraid. I think you'll do better posting your question in a model specific forum such as.....................
