I got mine(#37G), just like some of the other guys at American Classics Motors for $520... for a COMPLETE kit. I installed it myself, and got a HELL of a wow! factor out of it... You wil be very satisfied. There is some negative feedback On ACM, but I had no problems, in fact, the guy was very courteous over the phone helping me decide between the #50, or the 37...
