Ok, I'll make sure I wait an hour to post in the future!Try AVO, they are probably the only off the shelf company. I will cease posting now, Bruce beat me to it, he is quick off the draw is Bruce, does he live in the Wild West?
Maybe either AVO or Thornton, AVO are still available, sadly Thornton ceased to be.What happened to that suspension system that was always in the back of MPH? I can't recall the name.
