Funny... This is what I have been doing since my engine has been at the builder for an eternity. I've been welding and grinding patches for weeks for all the holes cut in the trans tunnel. Some knucklehead moved the shifter to what seems like the back seat and I finally decided to move it since the trans and engine are out. Best is what he used to patch the original. Looks like 2 gang electrical box blanks. I hit it with a cleaning wheel to see how much rust was actually on it while I was cleaning up the other bottom spots. I made a joke to one of my Dad's friends that I am not officially a hot rodder because I have been cutting my car apart and welding it back together.
You patch job is looking good to me. Keep it up!
