Bryant,
When you decide on the design that you want, you need to come over and we will stick some metal together.
Here's the one I built for Mandi's old Prairie, that was installed at a later date on a Foreman. We ended up removing the chain, and just using some quick links with swivel snaps, and we put a rubber mat over the bottom expanded metal so that the dogs would not hang a toe nail. Also put a piece of wood covering the rear bar, so that a dog would not hang a leg while jumping off the back of the rack.
