The Garmin pitch servo bracket is ready to be riveted to the bellcrank rib. The 8 rib rivets are AN470AD4-5 and the 4 skin rivets are AN426AD3-4. I was able to use my rivet squeezer on the top 4 bracket rivets and my rivet gun and bucking bar on the 4 bottom bracket rivets. With the help of my friend Frank Eddginton, I back riveted the 4 skin rivets.
