Autoloc doesn't make a bolt on kit of course for the vx. What is going to be a major factor is the bolts on the factory door hing. Are they stacked on top of each other or side by side? I have been contemplating doing the vertical doors for about a month on the VX but I haven't go the chance to actually sit down and look at the hing and the whats behind the front fender on the vx. The hondas are pretty easy most of them are bolt on kits. The prelude all have bolt on kits, I don't think doing vertical doors on the VX is going to be as easy as the hondas, mitsubishis ect.
