I'm a Ramones nut from Sweden.
I just ordered the MK 2 "Mosrite kit" that I will transform into THE Ramones/Johnny tribute :-)
At the moment I'm waiting for the kit to be shipped and while waiting I'm checking specifications, ordering more parts and just "plan" :p
IF you do happen to have the real dimensions for a Mosrite Ventures II headstock, please mail me or post here.
I'll get back with a build iary and more questions when the kit arrives.
