so i would need the whole dash off of a donor car? I am wanting this type of dash but i was looking at some pic and it seems as though the speedo cable plugs into the back of it. would you happen to know if this is correct cause i have a 460le tranny ad it has no speedo cable and i guess that the digi dash would not help me out either, what route would you take? i guess the only route would be to keep the dash and add a aftermarket speedo
