I would cut them to be barely snug. kools can telll ya how to glue them in prior to glassing. When I had mine done I had a 1" hole drilled thru each one. My cockpit drains were on the outside of the stringers and wouldn't let water drain to the garboard drain. Water would finally spill over, but it got sucked into the fiberglass and stringer *(fiberglass ain't waterproff.) Be sure to predrill the stringer for the motor mount bolts. and seal them with 5200
