I measured the frame of the 2003 rad support. So I went off those measurements to make a frame. I cut the bottom of the 1972 rad support off. Then I laid my frame on the back side of the 1972 support and tack welded it on. One of the pictures shows that part. I used 1"x3" square tubing for the frame. I made a bottom price, and two sides for the frame. The top is all 1972. After tack welding in the frame, I cut away the center of the 1972 support until it was matching the frame I made. I put a piece of 16 gauge sheet metal in the center and welded it in. Then I just measured the size of the radiator fins and cut out a square to match.
It's hard to put into words but hopefully that helps.
