Yes: The diff will stay in what ever range you leave it in with no vacuum. You Don't need vacuum to hold the diff. in ether high or low range. Mine was in high when I got it. After several years of driving it, I got 3/8s steel brake line and vacuum hose and hooked it up to shift on the go. Also got the vacuum switch to work and not leak by letting it pull in W-D 40 with the vacuum.There's a really cool reproduction sticker for the dash that shows the switch and shows how and when to shift. Mongo's Garage on this site sold me mine for $10. Google Mongo's Garage to see sticker.
