RV-8 flap spar to rib LP4-3 setting

How does one set the blind LP4-3 rivets that secure the rib to the flap spar? Bottom ones are clear and easy, the top one I simply can’t see how to get in there. Neither of my experienced blind rivet tools can get under the top flap skin overhang without risk.

This thing is amazing. Some RV12 builders bought them before the price went crazy. You may find one in the local chapter tools as well.

Thanks, combining ideas

My search skills failed me on that one. Adding the angle idea and grind away idea will do likely it. I’ve already flat ground the barrel of one of my riveters in building the -9A, but not the top. The top isn’t enough for this location. I was sketching a nut-sleeved bolt arrangement to pull it, but the angle shim may be ok enough. Thanks.
