    I am talking about the bolt that goes through the shifter and gets greased,


    looks like a 9/16, or some type of threaded rod with a retainer clip?

    :dunno: :1zhelp:

    maybe I am over complicating this

    I'm pretty sure it's 5/8 coarse thread. I'll check later this afternoon, and I might have an extra.

    they changed a few times..

    The bolt in my 74 K20's NP205 that broke off IN the adapter was a special shouldered bolt that had a 1/2" shank and either 3/8 or 7/16" thread! (I forget,it was 5 years ago when it snapped)..nothing worse than trying to shift into 4wd on a snowy day,and have the shifter drop down to the boot,and do NOTHING when you shift it!..:doah:

    After searching 3 boneyards for another bolt,I discovered other years had different bolts and adapters..so I ended up drilling the busted bolt out after yanking the "tunnel" cover up,and I re-tapped it for a 1/2" bolt,and used a nut on the threaded end to take up the "end play"..I also used a needle bearing I found in my junk drawer that fit perfect in the shifter,and had a 1/2" bore..I never forced the shifter after that!..

    I still thought the bolt alone was a bit wimpy...it should have some kind of a brace under its head bolted somewhere, to resist side thrust on it..GM goofed thinking a bolt alone would be sufficient..especially a shouldered one with dinky threads...:mad:

    Do you still need one? I finally remembered to look and found an extra.
