well, u should probably keep the bridge in the standard position, and just move the neck to account for the fact that it wasn't designed for an RG. In terms of the neck pickup, u don't really have to move it at all, but most guitars with 21 or 22 frets have the HB's spaced 4 inches apart (center to center) or if ur going to make a template off the RG u already own, then just leave then neck pickup where it is (less work). What ur going to have to do is find out there the bridge is supposed to be place/ where u want it, and from that, find the scale line for the brige, (i think it's 1/4" behind the whole for the floyd post?) lay ur neck on the body blank, then from that line take out ur long ruler and measure 25½" to the nut, once u have it placed correctly just mark a little line at the end of the neck that's 90 degrees to the center line of the guitar, that's going to be the bottom of ur neck pocket.. and when ur doing all ur routing, just move the template for the neck pocket up to this line, (make sure u keep it nice and square) and rout away.
ok, thanks, but Wes explained all of that bridge positioning stuff to me in another thread (and I understand it completely). I'll probably just take the positioning off the current RG. Since I had one weak vote for telecaster a while back, and nothing else on that, and a couple stronger votes for RG, I think I'm gonna go with the RG.
