Put mine on the ROPS in the same place as the original one using the same hardware. For the chain box I bolted it in the hole where the trailer ball goes.

I added a 40mm ammo box to the side of my L4330. It used to have a top, until some dumbsh$% put it on the rear tire temporarily and then forgot about when I drove, uh I mean when he drove off.
After poking around unde rear apron of my MF GC1715 I discovered a bracket with a couple of holes in it under apron... Hmmmm..... Some scrap aluminum from "resource pile", drill a few holes, some 5/16 bolts and nuts....
Next project is "slow vehicle sign" that rips the skin off my arm when ever I get too close....
