The inner connection to the front spar and front rib

You can see here that's is little tough to get to the rivets that hold the middle inner rib to the front spar and the front rib. None of the yokes I had would work. I tried the using a 5.5 inch Double Offset Rivet Set from Avery Tools in my rivet gun with a bucking bar, but it just doesn't have enought direct driving force to drive the rivet into the bucking bar. It just beats the crap out the rivet head. I am ordering a new set of 7.5 inch Rivet Shanks from Avery Tools to get the direct straight force I think I will need to set these rivets properly. UPDATE: My suspicions were true, the straight shanks worked great! I put an order into Averys tools and received the shanks the next day! Also, I learned that when using any longer than normal rivet shank, the pressure needs to increased. I usually bump the pressure up to 60 pounds for these long rivet sets, instead of the typical 40 pounds for normal size sets.
