Ugh. Work continues on the upper cowling. All the fasteners to the lower cowl are complete, however the ones on the top, which air now oversized fit about 3 or 4 and the others are now too large. Minor repair work coming up. The holes for the cowl screws are now both #40 with the left side needing a slight adjustment because the lower tab was too short. Not a big deal, but more work.
