Final-Drill all the holes of the E-1001A&B Skins and the underlying structure using a #40 drill. Start from mid spar and work way to outboard edges. Final-Drill the holes for the F-1023 Trailing edge perpendicular to the chord line of the elevator, not perpendicular to the skins.
I decided to machine two WD-415 Trim Cable Anchor brackets similar to the one being sold from another vendor. The brackets are much stronger than the Vans brackets being offered. The E-616 Cover Plates and WD-415 brackets where than fitted, drilled, dimpled, machine countersunk and completed.
The E-615 Cover Plate had to be dimpled so it could accept the E-615 plate along with dimpling the K1100 nutplates. The K1100 will accommodate the dimple for the screws in the reinforcement plate, but had to be dimpled for the nutplate attachment rivets.
This isn't the plate I used, I purchased a new E-615
