Have the rear lower longeron tubes cut to graft in new ones in the rear. decided to make an adapter to 'apply some compressed air to see if there seemed to be any holes or cracks leaking air out all the way to the firewall.
Immeditely I could hear a leak---- a small drilled hole near the rear of the rear seat area. Maybe a #6 or 8.

Anyone know offhand if this is supposed to be there? or shouls I weld it shut to keep the atmospheric moisture from entering ? Looks like its near the rear of the rear seat area where the floor sheet metal lays. There seems to be NO matching hole in the floor sheet...… I would think you would want that airtight--- just like a sealed strut...….
