'91 Chevrolet 1500 (GMT400) Body Mount Reinforcement

Though I haven't yet organized all my material on the '91 Chevy 1500 restoration I'm working on, I decided to post a little project I did to reinforce the body mount points on the frame of our '96 frame, which was acquired to replace the incredibly rusty '91 frame that was original to the truck.  I bought large diameter washers from McMaster Carr and machined the inside profile to match that of the body mount.  They came out great!  I only needed one, and a racer friend of mine came and welded it in for me.  Since he's a professional welder, he did a much better job than I could have.
