Center Stand Bolt Size?

[mattylmbr]

All -

Thanks in advance.

Bought my bike w/ no center stand, which is fine, but now looking to use those holes as an exhaust mount location. Anyone know the size/thread of the center stand bolts? Mine is a 1980.

Thanks!

The smaller, outer, holes for the threaded end of the pivot bolts is 10mm...
