Brief Description: Firewall - Countersink and Dimple
After all the match drilling I deburred any remaining edges and countersunk all the pieces to accept dimples in the firewall. I used two drills one for 3/32 and one for 1/8 holes. I countersink just past where the rivet fits flush so that the dimple will fit completely. Gotta be careful where you countersink. Some of the parts don't need it because they ride on top of another part that does.
