Thanks for the tip, Wil!  I'll check them out. 
The ones the local place were black oxide coating (does this rust 
easier, or protect well?) and not sholder bolts,
i.e. they were threaded all the way up.  I guess I'd have a bit of 
preference for the sholdered type, as well as
ones that were the original 45mm long rather than 50..  so I'll call 
King and see what they have.

I guess the stress wouldn't be pure static, but a lot closer to it with 
the spring buffering things and the suspension not moving very fast,  as 
opposed to some of the other suspension bolts that are more directly 
exposed to shocks from the road.  I won't worry as much on these..

I may take you up on the coffee can search,  I'll let you know...

Any other suggestions pro or con on surface types? 
Thanks!
