I turned my frame around today and painted the top of it. The frame is now done!!! I found the right rear frame #. After painting the rail, the number all but disappeared!! I also found a picture of the frame before cleaning. If you look close, you can see a very small part of the frame number. I included a picture of the frame cleaned, again, to save the time to look at previous pages where the picture is located.
I'm sure there are other Darrins out there with the number on the right side of the front frame rail???
