To mount the transducer I added nutplates to the rib. One nutplate was the standard two lugs and I drilled and dimpled for this one. The other was single lug and I drilled and did shallow countersinks for "oops" rivets to secure this nutplate. Cleaned and touched up the primer. Once primer was dry I riveted on the nutplates with the squeezer. On Ken's advice I cut off the unused section of the transducer manifold to give more clearance when mounting the upper cowl. I used the gun to rivet the contactor doubler to the firewall. Used the gun again to rivet the nutplates onto the contactor doubler.
