    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.
