71 Rupp TC driver key

[Joe51]

Hello,
Sorting through my parts. Have lost the TC driver shaft key. Does someone have the correct size/dimensions so I can get
a new one?
Thanks

Crankshaft is 3/16 so normally it would be a 3/16 square key (3/16" x 3/16" x 3/4" long). Confused on how you could lose the key since they are built-in to the 4 spline and into the fixed sheave pulley next to the engine? If it is the driven unit on the jackshaft then you want a 3/16" key that is 2" long.

Go to tractor Supply, get a 12 inch long piece of 3/16 key stock. About 4 bucks
