I was given a frame from a neighbor. It was behind the house when he bought it and knows nothing about it. I couldn't find the vin, assumed it was under the paint and used a wire wheel too aggressively. Now I cant make out the vin at all. Are there any other numbers on the frame that would help me figure out what it is? Or does anyone have any educated guesses? Anything would be helpful
