Finally got done welding (both sides) of the rear frame. It took a while longer to get done thanks to Dragon*Con and a trip to New York with Jeep #18 owner Boomerjinks. I thoroughly welded all sides of the frame with the plates and then hit them with a layer of rust preventing paint, and then black paint. It turned out great, but it makes the rest of the rusty frame really stand out now!
Here is the passenger side, the driver side looks the same:
Now to put the gas tank back in, and drive the Jeep without a top for a few more weeks before it becomes too cold to do so!
