I have single chamber Imco's on my 67.
They sound great.
Appear just as well built as a fm. The cases feel like the same ga.Thickness As a fm.
Longajevity has yet too be seen.

I wanted it loud out the back of the truck and I got what I wanted.

I got them at a end of the day swap meet deal at Carlisle $20. A piece.
