I'm working on a standard build RV8-1 doing the Showplanes fastback. The top fuselage longerons aren't designed to be perfectly level, so they are angled down/in some. It looks like the standard Vans cockpit side rails (which I don't have) have an angle bent along the length of them such that the outboard edge rivets to the top of the longerons flush, then the rest of the inboard rails are level. The showplanes cockpit side rails don't have this lengthwise angle, so it looks like they would simply remain at the same angle of the longeron.
In some of the previous Showplanes fastback pictures, it looks like some of the -8 (maybe pre -1) kits had perfectly level top fuselage longerons? What have others done that are doing a Showplanes fastback with a -1 rv8 kit?
