Outer Limits 4x4 Board

Hi all,

just playing around in the shed over the week, end and i ended up making some rock sliders out of some left overs. just wondering how other people have mounted theirs? welding is out as i still have to be engineered, pics would be great if you can post them,

cheers

The bolts will sit on the top of the chassis.

yep that's the design i had in my head and i think i have seen before, is this the strongest method? any other ideas out there?
