Exhaust Clamp P/N.
 

Amigos,

Help! The Cessna parts book lists exhaust clamps for my 1968 T337C as P/N 1250860-29, but this P/N is for 180 degree arc clamps, and they tend to leak at the bolts. The clamps currently on my Continental TSIO-360s are 270 degree clamps - they have an additional 180 degree arc shell welded along the inside of the outer 180 degree arc clamp, 90 degrees out of phase, so the whole clamp half looks like a 270 degree arc when viewed axially.

Cessna doesn't know the P/N of the 270 degree clamps, which I'ld like to get a hold of, rather than the original P/N 1250860-29s.

Does anybody know what P/N the 270 degree clamps are, and where they can be found?

Gracias!

Paul,
Can you post a picture of these clamps?

Thanks for the suggestions, guys! After calling a bunch of suppliers (including the ones you suggested, Herb), it appears the consensus is that Preferred Airparts sent the wrong parts - that P/N 1250860-29 actually IS the 270 degree clamp I'm looking for. So I ordered a bunch, they should be in at the end of the week, and we'll see then!

They'ld BETTER be right - at almost $20 a half - that's around $40 per clamp - I hope they're GOLD-PLATED!
