I am planning on doing a Factory five kit as well...eventually. I will be using a modular cobra as the donor though. They had one at SEMA in November and it was BADA$$! You should hide your Cobra, report it stolen, get the kit, insert your motor, tranny, brakes, IRS, etc... Oh wait, did I just say that outloud? But think about how fast it would be, how well it would handle and stop! Man I am getting excited!
