Sweet! Looks like my '00 in a red dress.
Dump the space saver spare, and get a $25.00 full size tire from a wrecking yard. Are you missing that lug nut up front, or is the chrome cap missing? First time at a tire shop, get solid lug nuts. The lug wrench won't turn the lugs without the cap. It's metric, and the cap brings it up to american std. Change the lugs or get a metric lug wrench to go with the other one.
Then,...
Slap a limited slip diff. in the back. Wheel it. Detroit Tru-tracs are great. Then get a tru-trac or a locker for the front.
That a D-35 in back? Looks like it from the outline. If you get a locker, it'll be ok untill you upsize the tires. If you really want to wheel it hard and big tires are in store, don't bother wasting money on the rear end(don't even get the limited slip. Start in front). Save it and get a D-44, Ford 8.8, etc.
