Flowmaster makes a muffler that is just about the right size. Sorry, I don't have a part number but it should be something a muffler shop can figure out based on original dimensions. They can customize the inlet and outlet pipe hole sizes to make it work. Granted it is not original and will not sound factory but if nothing else, it will do until you can find an original muffler.

Try Jim carter classic truck parts.
They sell Gmc / Chevy mufler for $ 50..

They also have some other parts for our CCKWs, unless orginal NOS is the only option for the restoration standard of your truck..

The chevy muffler pipes are too small for a GMC

As far as I know, there are no Chevrolet Trucks of the 30s-50s that use a Muffler with a 2 1/2" inlet, there are no After Market Mufflers that are an exact match for CCKW inlet/outlet wise. NOS still exist, but are difficult to find over here. Buy your spares now as these will not be around forever. I have found a source for original type inlet and outlet clamps, pricy, but nice.

I took my original (NOS) muffler when it finally went to my (good) local parts store and they found an exact match; inlet. outlet. dia and length.
It fit perfectly and has been on there for over 7 years with no signs of rotting out. It had a 1/8" outer skin as opposed to just sheetmetal.

And what line of Exhaust parts do they sell? I have 25 year old Walker, AP, Arvin, etc, books and the GM number does not Cross and the Buyers Guide(shows dimensions) does not show mufflers with correct combination of diameter, and length. The correct inlet and out dimensions on straight thru do not show.

I have no idea who made it. All I know is that it is very heavily built and is not straight thru and it fit perfectly.

Over the next few days I will go thru my old books, I hope I did not fling them, as I sort of threw out a bunch of old catalogs that were in the way last summer. The stack was 3' high and I needed the space. If I remember correctly AP had a straight thru with correct inlet/outlet but just the shell was longer than the original muffler, and overall length was way too long. I really do not believe there is a direct fit in present day aftermarket.

This was definately not a straight thru. I opened it up once to reduce the back pressure which I thought was a bit too much and welded the opening back together.

I doubt if it has any markings left on it beeing that old now.

I did not use one on the crane as it already had an exhaust system that was perfectly good.

I will be starting the Kompressor cckw in the spring and will install a new exhaust system on it with (hopefully) one of these mufflers which hopefully they can find again.

I have a NOS muffler which I bought from Marty Fravel I think back at an Aberdeen show a number of years ago. Still on the shelf.

Only reason I stick with NOS is that the components all line up and every thing is where it belongs when installed.

I saw a pile of tail pipes at Frank von Rosenstiel's yesterday. They are not NOS but maybe Frank has the whole exhaust. Worth a try anyway.
Cheers,
Barry

But if no one has them (NOS) anymore, what does the average (not Joel with unlimited parts) collector do park the truck until one shows up on eBay?

One of the trade secrets of the hobby is to find who supplies which parts, and make a list of those vendors.Many parts are very scarce, and you have to be quick to grab them no matter what the price. It costs money to support a CCKW, and a budget and restoration plan should be set aside. I am not rich by any means, but I learned to make sandwiches for lunch and cut out the $60.00-$70.00 per week on lunches /coffee breaks. We all want to drive our vehicle ASAP, but one should pace themselves,it may take a couple of years to do things right and within budget. One must understand that it takes years to locate some parts(wood steering wheels), I have some items that have taken me 20 years to find (NOS doors). We all envy the truck that is complete, but that took time. If one is real lucky, the hobby can support itself through the sale of unique parts.
When you discover a rare part, do not hesitate to grab it. The hobby is made up of all types of individuals, each with a different take on the parts situation. Some still believe that 65 year old parts are overflowing the shelves, others are realistic. I share a lot of thoughts with dealers around the country, and one of the frustrations is explaining that it costs money to find and ship parts, or advertising that rare part, and having customers hold off purchasing and missing out, as they believe the other dealers will soon offer that same rare part. The internet is great, as communication is instant, but parts are not.

One situation you can find yourself in is a Mexican standoff. That is in this case, someone has a rare part for a rare vehicle which very few people own. A particular model for example.

This happened to me at the VA national a few years ago. I found two original WW2 fuel truck nozzles that would be appropiate for my CCKW aircraft refualling tanker. One was $135 and the other $150. Too much for a part that would never see any fuel from my truck again. It would be there to complete the unit, not for actual dispensing of fuel. I did not buy them and found another pair a year later for a total of $60. Because I could wait (the tanker may be next after the Kompressor), I could shop around and wait for a better price.

Some times you fight for a piece (in Ebay). I bought an ACKWX original manual for $125 on Ebay. I bought the 2nd one on Ebay for $25. Both in nearly mint condition! The 2nd one was misrepresented and listed in the wrong place so no one else found it.

the problem I have here is the location , a long way from everything. E-bay and the help I get from this forum is how I get a clue on what parts fit what and what parts are right for my "45" . thank you all
