Injection pump pulley key

[91 ECO]

I have searched and can't find any posts on the size of the woodruff key that keeps the injection pump pulley aligned.  It's the only part that I have misplaced.  Where I live, only specialty shops carry metric sizes.  I'm thinking that it's 3mm wide because the 3/32" is too thin and the 1/8" is too big.  Thanks for your help.  I'm ready to get my Giles pump up and running.

I measured one with my el cheapo plastic caliper and got .12 inches which converts to  3.04800 millimeters
