Yes. The 390 clutch fork does not seem to work with the hipo bars that people are showing. The question is, are these correct assembly line style z-bars, or a later Boss302 style that superseded the original style. TSB, service replacement. If so then people would have had to change the clutch fork to the shorter style if they were replacing their original z-bars. If these are the correct style bar then the whole argument of "390 clutch forks on hipo motors", as shown in the parts books and supported by some of the more experienced in the Shelby community is a mistake. Waiting to see that one photo of the mythical assembly line z-bar or a good up close undercarriage shot showing the longer 390 fork installed. I'm going to put my ride together with a short fork and the B302 style bar that I paid a chunk for. I'll keep the 390 fork, that I paid another chunk for, until there is some sort of resolution one way or the other. Brian
