Ran into a problem.

The original coupling is 3/4" opening for the shaft. Repeatedly measured, of this I'm sure.

The key that it uses is 1/4" square rod.

I know this because I bought a 3/16" key and it was too small.
Swapped the 3/16" for a 1/4" and the 1/4" key fits perfect.

The coupling I bought from Moyer that is 3/4" only comes with a 3/16" keyway.
Called them and cancelled the order this morning.

Anybody knows where I can find an A4 coupling for 3/4" shaft using a 1/4" keyway?
Old part is reusable if necessary but I'd rather replace it.
