Personally, I'd leave the dash on, and move the key, and then find one of those little metal plugs to fill the hole where the key used to be, if I was restoring it. If I was going to leave it original, which I would with a tractor like yours, I'd probably leave it right where it is.

That wasn't me with the 770, but I did see the ad. I was trying to figure out who had it for sale without actually calling, but never did. How did you find your Super 77?
