I managed to get some beefy sliders/running boards built from someone in the US. It seems everyone in Alberta was too busy to entertain this project. There is a reasonable demand for such a product, so if anyone ever builds a jig, and starts making these, I am sure they could fill a lot of orders! Mine ended up as bolt-ons, but are mounted lower than I cared for them to be. It seems the e-brake cable location was an issue. If you are interested, I could post pics of what I have?
