2.5 hrs 36 rivets.
Sanded the tank nose reinforcement plates to shape. Match drilled the outboard plate.
Used the tank nose attach bracket to drill the inboard rib, and then match drilled the inside plate.

Cleaned and then primed the tank attach brackets. But discovered I forgot to countersink for the flush platenut rivets. So did the countersinks, and then riveted the platenuts.

Pulled the capacitive tank gauge kit to get ready for installing it.
