Marman Exhaust Clamps/Flanges... Where to find?

[Kawgomoo]

If anyone out there knows where to get the flanges that m900 trucks use on the exhaust. I would greatly appreciate it.

These are basically 4" v band clamp flanges, however the ones on our truck are flat on both sides. Instead of flat faced with an angled back.

I know Clampco makes them, but have not yet located a distributor of theirs that know what they are. Trying to find another source. These should be fairly inexpensive, as they are just stamped mild steel with a double rolled flange.

I would guess any big truck parts house

We only have fleetpride out here. They are useless. In a city of 4 million, youd be surprised how hard it is to find anything here.

Back east im sure i could walk into any one of ten ag stores and have it in my hand.

Google isnt turning up much. ive got part numbers for these flanges from clampco, norma and eaton. but a search of the number nets zero results. these flanges must be supplied to OEMS and not the MRO market.

original supplier is Donaldson on the M939 muffler. Not sure on pipes.

Thanks! Im going to try and find them, see if they arent still around. I did find one manufacture of this style clamp that some peterbilt stores carry. So im getting warmer! Now i just have to find them for the right price! {im cheap}

Found these flanges in the donaldson catalog. Which, led me to a local mack dealer that has them in stock.....but only in 5 inch and up!

i'll get there....
