How’d you mount your rear seat/cargo box?

I'm wanting to install a rear seat/cargo box. However, due to the Polaris Sportsman flat rack with holes, it's looking a little tricky for me. Besides using u-bolts does anyone have ideas how to do this? I saw some plugs that expand when you screw them in on Amazon but the reviews say they don't really hold well and a seat could be dislodged.

Thank you for any advice or links!

2012 550 X2 Engine lunched.

Newbie here.
Just got back from a trip to camp. My engine is trashed....hole in the block the size of a softball, starter torn out, connecting rod busted. The left side balance shaft came through the case and hit me on the inside of my left leg and landed on the running board, along with part of the case with the dipstick still attached. Not hurt. I will attach pics soon. I am just starting to dissect this to determine the cause of this failure, still too early to tell.
Anyone else have this type of MAJOR engine failure?
