Assume (correctly) that the brakes, shocks, hoses, belts, guibo, flex. brake lines, etc. are ancient. They may work, but they tend to be OLD. The clutch will likely be feeble, also your balljoints, tierod ends, & your shifter will have slop to it. Worry about basic operation and basic safety first. (headlights/taillights gotta work, engine's gotta run w/out overheating, it's gotta run w/out needing a battery charger each time,etc.) Check your windshield seal and rear window seal; probably rock hard and leaking, causing rust around the edges of the windows. Later make it a beauty and think of a hotter cam and a five-speed upgrade....
