Welcome Russ, we do our best to help ,doing the tank is easy first remove spare tire , second there is a hat like cover to remove some are bolted from under the car5 bolts remove cover looking down that is the top of the gas tank four bolts at the front and at the back at this point you can remove it 2 ways slide and drop or remove the rear cover and lift out after sitting that long it is a good idea to clean the old gas out and clean the scale out of the tank it should be aluminum You bought a good winter project car getting it all ready for spring and a lot of fun driving ,,,,,,,,,,,,,, Dan R
