Well, if you have questions, ask away.
Like I mentioned, most don't know the 8-3/4"' and Dana 60 wheel bearings need to be greased.
Originally, the pre-1971 cars have left hand wheel studs/lugnuts on the drivers side of the car.
Usually there are either in broken/poor condition or have been replaced with right hand threaded studs and lug nuts.
Just mentioning if your going to pull the drums/hubs/axles to grease the bearings and check the brakes.
Power steering can feel sloppy. you can adjust some slop out of the power steering box.
If the car still has the original exhaust manifolds, check the heat riser valve is not frozen. If stuck closed it will really heat up the intake manifold.
Check if the bulkhead wiring has been modified, and that the car still has the fuseible link. Usually cars this old have had the wiring messed with.
If an automatic, check the kickdown linkage is present and adjusted.
Usually if the car still has the original fuel tank and lines, they will be in pretty bad condition. Not unusual to have to replace them.
A new replacement fuel tank like the spectra premium cr9 is less than $200 ($167 on Amazon). They also sell an EFI version with intank walbro 225 lph pump, but I think it is around $500? Holley sells the Tanks Inc EFI fuel tanks for their sniper EFI conversions too.
Many of these cars have been converted to electric fuel pumps because they are not driven daily and it takes several cranks to get fuel to the carb when the car has been sitting a long time.
Electronic ignition is also a common update for those not wanting to maintain the points ignition system.
With a stock alternator, it is normal for the battery to be discharging at idle and the light to dim as the factory alternator does not output much power at idle, but once RPMs are increased the alternator should be charging the battery.
What else can be an issue:
Rust around the rear window, trunk floor and trunk extensions is common.
Water might leak past the wiper pivot(s) if the seals are bad.
If it has the original springs and torsen bars, the car will be sitting lower and the suspension will be real soft.
Some spray lithum on the door pivot pins and door lock, hood hinges, speedometer cable and accelerator cable.
Often the accelerator cable will be rusty and frayed on an original car this old, so check if it needs replaced.
On small block cars, the accelerator cable is usually too short when changing from a 2-bbl intake system to a 4-bbl intake and carb, and the linkage bracket will need modified to fit the new manifold (it's not as simple a swap as many make it sound.)
