Thanks so much Delton. In reviewing the reference photos I have, I see you are correct on the vertical tube on the right side. I moved the right side one and took out the left side. Was able to get some bench time in and have been working on the axles. Rear one is done which includes the brake. Front one is a DM product but with brass ends and all soldered together. Finishing up the alterations and other tasks on the frame then it will get a coat of primer and a then a coat of semi-gloss black.
Thanks noname and Bob. The rivets on the driveshaft tunnel are actually only holes pushed in with a needle in my pin vice. No actual rivet. Some of the areas like the angled part of the firewall have rivets and those are from Scale Hardware which has since closed.
