36mmx24tpi likely for the BB shell (both RH as it's likely Itl)
25.4mmx24tpi for the headset (or English 1"x24tpi, they are class B+ interchanges)
M5 bottle bosses and drop out eyes

But as they say, measure twice assume no times. Andy

Haha, No I wasnt kidding. And thank you for the info.I will take that info and use it as a starting point.
