Welcome to Mud and the Cruiser addiction. Congrats on a stock find in decent shape and the supercharger to boot.
Coolant system first as people have said... all the plastics and hoses as well. Then some PM and some fun.
As for towing the disco id say flat ground with a light brake equipped trailer maybe. I wouldnt head for the hills with high hopes.
Youve got a couple great clubs nearby. Check clubhouse tab at the top of the page for other nearby clubs but up in clemson area you have
upstate cruisers and down by you there is the
low country land cruisers. Olde north state cruisers and georgia cruisers clubs not too far away either.
ONSC is hosting 3 day affair at Uwharrie if you want to come out and meet lots of folks and check out different builds. Reg is open now online
