OK, I had the same problem with my 1990 Cadillac Deville. Had to go to a junk yard where they gave me the entire bolted on assembly. I got a 3/8" impact wrench and unbolted the belt buckle from the frame, and did the same to the one on the assembly they gave me. After that my buckle worked great. The color even matched the old one.
