Thanks, the website is helpful, but it'd be nice to know the number so I could just do a search.

I took my engine apart and measured a few things. This is what I found:

The reed thickness is exacty .006" on my engine. And it is the later, non-recessed type.
Took the ring off the piston, and shoved it in the cylinder with the head of the piston and measured the ring gap. No kidding, it's .071". I couldn't believe it either. So I checked again and measured the feeler guages with a micrometer, .073". I think I'll be ordering a piston ass'y. Does Frank Bowman do rings for the two-ring setup? Would that be necessary? I need a new piston anyway, mine is scored up pretty good, so I may as well get the two-ringer.

I'd like to hone my cylinder, as it has some scuffing. Would a brake cylinder hone work for this?
