Hey Ron, for your Reese fifth wheel hitch the correct wedge is supposed to be the Reese part # SWW-03 but like you noted Reese is down on their luck and none of their products are currently available. The most similar one that is available would be the MORryde part # MR44ZR which was designed for Reese Select fifth wheel hitches. Is your pin box a Sidewinder?

@Ron makes sense! That was the OEM version of the Sidewinder. The wedge I mentioned does fit that too.
