Howdy,
When I bought my 95 Kat, it didn't have the mirros either, and I wasn't having any luck finding correct bolts. Fortunately where I work I've got access to some pretty good tools. I drilled and threaded the holes to 1/4-20. I don't wanna have any more trouble if I gotta find new ones sometime, and I've got a lot more choices now.
Now that I park my Kat inside, I gotta have the mirros off to go through the front door

.... I have them off most of the time, and I'm trying to find a way to smooth out that half-oval indentation.
