[Roadsters] Valve Adjustment Parts Help

[Alan Watt]

I was installing the rocker assembly tonight and attempting to adjust the
valve lash and discovered the number 1 exhaust valve adjustment stud was
stripped.  The threads on the rocker arm are good.  Does anyone know where to
get a replacement?  Any chance a auto parts store would stock such an item?

The threads appear to be a 3/8 x 24.

Thanks,
