Has anyone used one of these setups?

Looks to be reasonably easy as far as fabricating it up and paying for it to boot! Having not actually driven my truck under it's own power, I can't say that the front suspension needs upgrading. However, I am also looking to convert to 6 lug disc brakes on the front at some point. So this might be better at some point from a parts availability standpoint. Since I'm not doing a 100% restoration, but more of a restoration and make it a daily driver, I'm interested more in the parts availability and performance aspect of things to come for the next 40+ years.
