Tylor, take the truck to a mechanic that knows 4 wheel drive trucks. There could be so many problems with this truck that it would be difficult for the everyday person to spot even the obvious ones. Are you mechanically inclined? Because with a truck this old you stand a good chance of working on it more than driving it.
Not trying to rain on your parade, but I have 'been there and done that'. Consider that parts may be a problem.
And is the truck a 4 or a 6 banger? If a 4 cylinder then those over-sized whells need to come off.
If you have the 'Hots' for this truck , try to wait awhile to cool down. You will make better choices then.
Good luck
