On the straight stack exhaust, there are cool cam-type clamps around the header tubes. I think there is also supposed to be one around the mid-stack, though mine only has a mark where the clamp once was. Are these cam-type clamps still available?

Thanks

I think they were made by Tinnerman. Run-of-the-mill worm type hose clamps work fine...

If you have to have original, try either Preferred Air parts out of Ohio(they stock lots of old aircraft parts)
Yingling out of Witchita
or
Find an FBO that has "Parts base" and have them plug in the part number. Some FBO out there may have a part laying on a shelf, collecting dust, waiting for you to broom it off

OK:
A3122-30-59 23 available Western Aero Services, Inc. Denver, CO
A3122-52-59 6 available IAG Materials, LLC., Miami, FL
A3122-58-59 Couldn't find any.

Many thanks
