I'm missing a couple of parts on my 350 WC steering head assembly. Specifically, I'm missing the upper race and the screw down lock washer. I was able to source a complete front triple/stem assembly from a 160 Jr which has both parts I need, but I wanted to know if the stem diameters were compatible.

Can anyone provide some insight?

Thanks,
Steven M

Refer to the parts lists for both bikes.
If the parts are the same they will have the same numbers too.
