Ok, on the forward fuselage skins top row of rivets, what kind of bucking bar do you use to get to the rivets inside of the landing gear boxes? I don't have anything small enough to get in there...

I used a small tungsten bar, something like 5/8 x 1 x 3", it is a challenge but can be done.

I recognize it's heresy, but I used a number of pull rivets in spots that were just crazy silly to buck... I figured it was better to do that than to have a bunch of drill outs...

If you can find a pointed/or tapered bucking bar to fit in there, you can turn the pressure up a bit on the gun because the thick material in this area is so robust - it doesn't easily deform.

Emailed Van's and got the OK to use Cherry Max there. I thought, why kill yourself and increase your chances of pounding a bad rivet. Did the same for a couple more that are right behind the roll bar bracket bolts.
