I tried googling your boat, but didn't find too much. There is a Yahoo user group for the Puffer, but I didn't follow it.. cause I don't like Yahoo..
If you don't get any action here, I suggest you follow up on some want ads and ask the sellers what they know. If you could find some local puffer owners that would help, but you're probably already tried that....
Finally, the company that used to make these boats is still making Sunfish. Perhaps they could direct you to a source of rigging info. Google "Sunfish Sailboats"
