Located and drilled #40 holes for the air seal clamps on the bottom cowl. Final matched drilled with air seal clamps, both left and right sides. To complete, I need some contact cement (plio-bond) to attach the air seal to the clamp, prior to using #6 screws to attach to the cowl.
In the meantime, proceeded with cutting the alum spacers needed for the oil cooler.
