Hey General, just had an idea.....grab another EX-5 kit and use your Moderne as a patern to draw an outline to cut down the Explorer. You already have both and at a glance it looks like there would be enough meat in the EX shape in all the right places to make it work.
When I built the EX-5 & EX-1 both bodies were exact same measurements except for neck pockets due to one being a 6 string guitar set neck & the other a bolt on 5 stringer bass neck.
