And the voltage regulator I cut a hole in the insulation so it is accessible in the future.
We decided to try the radiator before calling Bob. He used a heavy duty core so it is a bit thicker than the original. He warned me I would have to cut about 1/4" from the upper radiator rail. Also the '73 Dart side supports I got just a smidge to narrow so I had to do a little work to get the radiator to slip in without damaging the fins on the edge... We are going to leave it in for now where it is safe. When we take it out to install the power train we will touch up the paint with some white epoxy primer and no one will be the wiser...
PERFECT fit....
We restored the starter relay (will see if it works some day), ran the wiring and wiring clips, installed the new windshield washer parts and called it a night.
