Wow Rich, good eye!! I just checked that seam at the bead and you are right, it is welded! I had to run my finger along it to feel any signs of it being welded and there are some slight raised areas where the weld is.
Talk about craftsmanship, that seam is almost invisible!
I am pretty sure that muffler is original also, so where do I get an extra lug to match??
Thanks again
