Lower core box vents are covered (sealed) by the lower core box frame. Grimsby caught design error, corrected in their models, & put into tooling. Update design based on Grimsby parasolid model attached. In addition, the bushing holes are blind. Being blind, the holes do not drain after being in the cleaning tanks. Add slots (6) places to lower frame allowing cleaning solution to drain out. Grimsby also made this change. Again make change based on Grimsby parasolid attached.
