Ford Blitz Restoration/Rebuild

Tony, With your skills (eg battery) you can make the domed ends (out of a heavy gauge steel) along with the rest of the muffler.
I think some muffler manufacturers use pressed ends still, but put them together the other way around.
Failing that, I reckon someone like Colin Jones would press the ends to your spec, in the wink of an eye.
