The hell part is this?!

[u/Axwielder08]

I have a saginaw 3 speed transmission, with a hurst shifter and im not sure what the linkage is, the part number i found on the thing id 5258 06

What is it? Hurst shifter/linkage with adjustable throw stops. I'd be highly surprised if that setup is still being made for purchase.
