That's what I've taken away from it at this point. It's a money pit to chase after the feature. After you get the button and the computer, who knows what will follow that and you wind up chasing it one purchase after another. The 4wd in my 1958 is already superb so I'm not going to worry about it. It would've been a no brainer if just putting the button in was all that was needed though.So, is the consensus that it would be too much tear up to get the MTS working in a 1958
