Tony, best thing to remember with "survivor" type cars: less is more......keep it clean and well maintained but try to advoid cosmetic maintenance if possible. I faced a similar situation with my 70 black L78 Nova...pretty much untouched original car....a little paint work done in the late 70's, but nothing else. If you are concerned about rust or oxidation then coat the parts with WD-40 or some other suitable protectant. Keep any and all maintenance items you remove, eg; fan belts, hoses, clamps, fuelpump, brakes, etc....store and label all of these items for future historical value and reference. Most of all...enjoy it for waht it is, a time capsule of our hobby!
