I fired up the band saw and cut the foam for the bulkhead C, D &E from cardboard and or foam. I found that binder clips worked well for holding things in place while doing the work on the band saw I also broke out he fiberglass and cut the layups for C, D and E bulkheads. I also found out the little indentations on the fuselage shells are for Glasair quick build reference. I had a set of them on the shell just forward of the bulkhead B location. Harry was quick with the answer that B goes 37 +/- 1 in from the forward edge of the rear joggle as the manual states.
