anyone know where i can get some 8mm chainring bolts? that's 8mm in diameter (as opposed to the 10mm standard). i stupidly chucked the original doubles for the thun aero coronado crankset i'd like to re-use before i realized they were non-standard. they were slightly stripped, although probably usable.

the crankset and chainrings are in pretty good condition so i'd rather not drill out the holes.

(i already posted in the classic/vintage section to no avail, and as this is a single-speed conversion, i figured i'd ask here.)
