Been there. Easy. Tape the smooth faces of the glass pieces with masking tape, painter's tape, or whatever you use... both pieces.
Stack them just as you would while building the bow... glass/maple/maple/glass... smooth glass sides out. Wrap them with tape in three or four places to hold them together as one.
Draw a longitudinal line on top of this stack at 1 3/4", or set your bandsaw fence appropriately.
Cut them to the line.
p.s. It will help with splintering on the bottom piece of fiberglass if you either use a perfectly flat board or another lam on the bottom of this 'stack', and/or have a zero clearance blade insert in your bandsaw's table.
