I happen to have the same gauges and it only took me 2hrs to tear everything apart and install them, and that included shooting a damn needle stop around the room and wasting 20min trying to find it, but I did! So if you're slightly competent, it's not bad at all. Also, I just eye-balled mine and everything matches up pretty damn good. They don't sell two-sided scotch tape in International Falls, they don't sell anything here! But I just taped the corners w/electrical tape and you can't see the tape w/the bezel on and they work great! Except for the occasional tach needle stick ;-) So I guess a little rework is in order, but when you live up here there is nothing else to do anyway! Good luck to all who try!
