A few forums back there was some discussion on the part number(s) of the muffler used on the WDX/WM300. I saw a post saying the inlet and outlet diameters were different. My muffler's ready for replacement and I've noticed a part number of 83901523 on it, does this number come up in anyones parts list as an original for a B2PW? I went to the Walker muffler site and found listings for 40's-50's vintage 6 cyl Dodge trucks using #21028 or H.D.#21169. The 21028 has a 2" inlet and 1-13/16" outlet. The 21169 has 2" in and out. They didn't list the WDX but I'm assuming the chances are good that what they listed was pretty close to the o.e.m. Anyone have any other aftermarket part# for a reasonably close replacement?
