Here is a picture of a frame I bought on Ebay. I bought it because it came with the body I wanted. I was going to use it, because I was attempting to build a rod for $ 3000 but my Son kept hounding me to scrap it as he didn't like the way it was built. Finally, he talked me into it, and he actually cut the frame up and made a base for our sheet metal brake. He did that so I would never be tempted to use it as a frame. After he cut it up, I was glad he did, because the welds did not penetrate deep at all, and they used a piece of water pipe for the front crossmember.
Now that I look back on it, he was right. This frame was pure junk.
