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.

Easy peasy with it all apart like that and must be done now!! Use a bucking bar with an offset foot.

I had to remove the roll bar attachments then put them back in - - 25hrs. eeek!!

I used an angled bucking bar, it is just a piece of structural steel that has been cut so that it will fit. It is the one on the top left in the picture.

I ended up grinding down a bucking bar to get it to fit. Moving on. Thanks to all.
