Are the digital units interchangable with the manul lever units, If so are they direct cabel cahnge or will there have to mods, made to the wiring and vacumm lines??

 

about the only thing the same is that they will fit in the same space in the dash.

There are a lot of things different. I am not saying you couldnt do the swap but you would have to have a FSM with wiring diagram and a parts car that you can get everything off of.
