Thanks Robbie.
I have no idea when the pin fell off. Maybe as I was getting onto the on ramp; perhaps it was loose and fragile in the preceding months.
As for the fix: I suppose I would also have to grind off the head of the bolt as well.

I am continuously aghast with wonder at the amount of service our cars will provide us while missing
critical parts.
YES there should be a pin inserted into the front shift bushing!
I typically "massage" the parts into slightly less slop than this. But uhhhh, yeah you should probably have a complete and functioning chassis before you go adjusting the stop plate.
If I remember correctly, you can drill the remnants of the old pin out, grind off all but the last few threads of an M8 or M10 bolt, and use a jam nut to hold the bolt in place and shift for the next 100 years without worry. Welding in a hardened steel pin would be ideal, but above my skill level.
Unreal, how you even drove that in the first place…

Holey Katz. How on Earth? James, follow the above Air Schooled instructions . . .

Ok, apparently, I'm not the only person with this problem:

This bus owner has come up with a pretty slick solution. I don't know how he fabricated the bolt, but maybe I can conjure something comparable.

Their solution looks like a custom machined part (lifted from thread:)
I suspect you could use an M10 bolt with the head cut and rounded off, and two nuts instead of the machined-in collar.

Robbie,
Yes, it looks very skillfully fabricated.
Questions, if anyone knows:
How far forward does the pipe bowl ride on the pin when going into 2nd or 4th? Will a nut on the back of the welded bracket interfere with that movement?

You have about 4mm in 2nd and 4th. The locknut can be ground down by half if interference occurs.

A jam nut (think valve adjuster lock nut) should be skinny enough.

So to follow-up and close this chapter of transmission drama...
The main event of my IAC visit this year was addressing the missing shift rod pin. Here's how it all panned out: M10 bolt, sans head, smooth shaft and 3 nuts to lock it all in place.
The nut on the back of the welded bracket just kisses the bushing at the end of the pipe bowl when going into 2nd or 4th.
So far, so good. Still a little notchy in 1st and 2nd, which is perhaps attributable to the newer tranny. But here's hoping this is a permanent fix.
Thanks for all the good ideas!

Your phone puts my myopic astigmatized camera to shame. Still shifting well? You may, at any time, check the security of our locknuts.
