I think I know where you can find the linkage parts you're looking for.

There's a place in Galesburg called Midway Auto Parts. And there a few old squares with manual transmissions in the yard.

A bit of a drive from Lincoln, but it might be worth it.

Also, I think I bought a Saginaw 3 speed, Clutch, and Flywheel from you like 2 years ago. My old clutch was slipping bad, but that new clutch I got from you is still holding strong.

Depending on budget. Consider a NV4500.
