Larry, Quite honestly, I would call Jon up at Brazel's RV Performance and ask him. They have the experience and all the part numbers that you might need. If the component that you are looking for is a non-high pressure component it most likely is a coach builder part and not listed as a WCC part number. A/C is not my strong suit and I defer expertise to my service center, Larry's Auto Clinic in Myrtle Beach.
Thanks for the info. A mechanic??? at a company, that is no longer in business, either removed or loosened the half shaft for some unknown reason. I had to tighten the nuts while on the road (slinging oil) and I reserviced the rear end. There is still a slight leak so I thought if I had the torque values I would tigthen them to spec.
