They didn't have a package by the name "Up Country" back then. They had an "off highway" package, which was heavier springs, skid plates, and tow hooks. I believe it dod NOT raise the ride height.
Tow hooks can disappear. Check your gas tank. If it has a 2-piece rubber/plastic shield, it does NOT have the off-highway package. If it has a very heavy-gauge steel skid plate under (and around) the gas tank, it has (or had) the off-highway package.
