Speedo a no go.

Thanks torque shaft bushing. Ordered. Looks like they have them on classic industries too in case anyone stumbles upon this thread in the future.

Speedometer cable ended up being the wrong one. Transmission side was the wrong size. Found a cable on C.I. I'm gonna try since I've exhausted all of my local shops and have come up empty handed.

Never thought a cable that spins in a hose would be such a pain in the ***.
