Crank accessory replacement

A quick learner from 95066 says:
Was about to buy qty=5 of
Universal Joint With Pole Ring, 11/32", 39-336, bronze.

Well, 11/32 =.34375, which is slightly greater than the presumed 1982 Truth brand crank spindle i want to put the 39-336 onto.
I measured at three points (rod, gear, inner rod) = (0.336, 0.311,0.25).

I don't know that much about window hardware, so i wanted a sanity check before ordering.

ps - Enjoy your holiday.

Thanks for contacting us! I think the 39-336 will work for you, yes. If your operator is Truth brand (and it appears to be) then the 11/32" spline will be perfect.

I hope you had a good holiday, as well. Happy new year!
