I'm thinking of welding up the holes that aren't needed in the upper front bulkhead rather than putting in the rubber bungs, I'm not exactly sure which holes I need and which I don't, I clearly didn't take quite enough photo's when I dismantled the car, I can clearly see a couple that are bunged and some that are used but I'm not sure about the rest.
I wonder if anybody can help me identify which ones I can safely weld up that I won't subsequently have to open back up after painting??
I've marked in Green the ones I think I need to keep and red the ones I think I can close, the rest I'm not sure about....
I think the square holes also had plastic nut inserts in them that I guess I could if I felt like it close up and replace with a rivnut?
