I'm not worried, just considering asking for some to be put in before paint, so I can Waxoyl the rear triangle, or leave them sealed off as they come now. I'm not asking for advice, just was wondering if the rear vent holes were sealed back in the day, as you've just rebuilt one, but no worries if you can't answer that.
sorry woodsman, i thought it was a concern of yours as you were buying a new frame, not worrying about mine, sorry my bad....!!!!, as for my frame no it dosnt have rear drain/vent holes and neither does my lloyd, from memory, ill have to look at my konas in the morning its getting late now, !!!!!!! but back to my original point after 12 years, the frame is great shape, no signs of rust what so ever, (unlike my lloyd when i got it...lol....
) so i would certainly not concern yourself with it too much, you sound like the sort of fella, that looks after his kit and certainly takes pride in it, so good luck with it, and i shall look forward to seeing it?
again sorry for missing your point...!!!
