cant see at all how it could be legal do to if line faild ud be in deep**** in hurry! if line fails on gearbox u can strongarm it! i drove my rearstear zuk buggy on road all time with matchd parts from psc didnt drive bad but like yellowjacket i would keep speeds down. dont think a trooper would ever look at sumthing like that anyways. Ky law like law in mexico anyways!
