I am in the process of gathering the parts to redo an early 55 p/u. This will be a daily driver and I want to upgrade to ifs, auto, V8. Have looked at many MustII setups and there are only a few that look like they will hold up. These are the ones that have the xmember and the spring hat solidly connected to each other and the frame. Thought I had my mind made up until today when I saw a kit from Flat Out Engineering to upgrade to corvette ifs and irs. Can't find out anything about these folks other than a few conversions done by magazines on the web.Looking for comments on Flat Out before I call. Anybody??
