Joe,
I also enjoy your restoration's progress. Keep us updated. With my first GS restoration, I detailed the frame first. Then took it to the body and paint shop. We covered it in plastic the best that could be done (I thought). However when the car was ready to be picked up, I was not happy with the shop. The plastic was ripped and in disarray. A lot of dust and overspray was all over the pristine chassis. Took a lot of time and effort to clean up and repaint over the overspray. A little over spray is okay but this was nasty. Therefore, on my current project (my second), I decided to have all the body and paint work done first. Then pull the body off and work on the frame. At this date, the rolling chassis is detailed and back together, ready to roll back under the body. So, I would suggest doing the best job possible with bagging up your beautiful, clean frame once you get it at the body and paint shop. Good luck.
BTW, Classic Tube made my fuel lines in stainless steel. They had the pattern for the fuel line but not the return line. So I sent them mine and they did a great job with them.
