F-7106 Fwd Top Skin - riveting aft three rivets to side skin/longeron

How did you get a bucking bar on back of these rivets?

Due to the canopy deck, there is a thin gap to get the bucking bar in there.

Modify a bucking bar?
Thx

I have a thin tungsten. If memory serves, that's what I used. Same on the 7.
