The long rod, 3-4 shift is fine thread. BB and SB.

I went back to my high res photos... and what Mike asserts is true on my shifter rods..  ie.  The long 3-4 rod has fine threads, the others are coarse thread. And note on OE rods there is only a single jam nut.

But this does beg the question:  WHY???

My guess is that because the 3-4 adjustable rod end is the only one that is internally threaded, it was done this way to allow for a finer adjustment when one revolution was made.

Mike - seems like a good reason to me.

Gary - the rod ends look correct for original GM.

Mike,

That makes sense to me also...  I noticed the different mechanism, but hadn't thought about that approach meaning that adjustments would have to be made in complete rotations.. :)

Good stuff!   Sure helps to have some experts to answer our questions.. :)
