I have a chainsaw filing vise; it's used to secure a chainsaw while using both hands to carefully file the chain, when working in the bush.

Instead of strapping the vise to a log, or strapping it to a tailgate (too loose), I want to attach the vise to a clamp that can be clamped to a pickup truck lift gate.
The lift gate is similar to this: https://www.amazon.ca/LiftDogg-13006039-2-Piece-Pickup-Liftgate/dp/B00P3OALCU
I suspect the vise wasn't designed with a clamp attached because normal tailgates are unsuitable for clamping, unlike a heavy gauge steel lift gate.
What kind of clamp could I use, and how could I attach it to the vise?
