RV-10 Upper Wing Root Fairings

Why are the rivets marked in red …..470”s and not LP4’s ?? The rest of them are. And how did you get a bucking bar on them?
Thanks

I also wondered about those rivets at the back by the flap torque tube and rear spar passthrough. The only reason I came up with is that they are 470s because there isn’t room to get a tool in there for pulled rivets. I used the long RV-10 bucking bar (and cussed a bit).

The rivets at the front are easier to access.

I used LP4s on all of them. I didn’t want the airplane getting used to the taste of my blood after trying to buck all of those..
