It seems that it’s a rare piece at least if the parts books are correct. I found a part #379656 with a 27/32”-20 thread listed. Does that sound correct?
Thank you,

That might be an e$$$pensive approach, but it's a "last resort" possibility. That thread diameter and pitch is a real oddball- - - -no wonder they're scarce!

Also used on 3/4 ton 3600 models in case you are searching for a serviceable used one. There is an NOS pair of them offered GM# 379656 * in this eBay ad. A number of others offered in singles and multiples, but this one seemed to be the best price deal. Should fix your buddy right up!  *NOTE: As usual the eBay ad descriptions lack complete info on models/trucks these were used on.

Now I know why. We’re hoping to find a good used one. | | | | | Joined: May 2007 Posts: 226 'Bolter | | 'Bolter Joined: May 2007 Posts: 226 | Thank you! To Glads51.
