Hi, Does anyone out there have a spare A10 etc. primary chain case bolt to sell. One of mine has escaped.
Cheers, Rick.

C&D autos are very helpful guys for bits. They advertise in the Star monthly mag.

I assume you mean one of the chaincase cover screws? They are not all the same length but the majority are part 65-3063 which is a 1/4" x 1.75" BSW screw. The original ones where slotted screws but many replacement are Allen screws.

Yes, I mean the 1/4 X 1.75 inch with allen head.
