Ok, first thing you NEED to get is that bumper, if it is in really good shape, and maybe the bumper lights.
In the interior the thing you need is the armrests, the red painted ones are ugly!(armrest.. is that the name?), also get the clock if it is good and cheap, just in case.
Front wiper motor is good to have an spare just in case, the front one works alot (in rainy places).
Exterior trim: The chrome parts around the lights that follow in the hood and under, those are IMPORTANT, grab them if you can. If the one around the grill is cheap, get it also.
Mechanical important parts: The ignition module is an important thing, also an spare distributor, the carburettor, camshaft (if in perfect shape), main rad fan (motor), fuel pump...
Geez.. i am missing some important items now, but i will update when i remember
Note: If you find a roof console, get it! Its a nice bolt-on extra for your car,
(and has a lot of buttons to play with).
