rwise,
Do you know how the muffler itselfs is strapped to the curved muffler bracket under the bed? Here's a couple shots. First was taken when I was replacing the front bed rail. Your muffler strap should be a long piece of strap material and a eye bolt connected to one end with bolt and washer. It's hard to explain how the strap is routed and I can always scan a picture for you if necessary.

Oh yes, I assume a '49 and '50 truck were configured the same in this area.
