Re: 66Vert Sway Bar Link issues
You can probably replace that link, and a pair of shock absorbers, if necessary, without jacking the car up. On the ground, you could measure how much space you have between the tire and the ball joint so you can start thinking about new fat wheels and tires.
If you do jack it up, get someone to turn the wheel while you look at the pitman arm, the idler arm and the tie rod ends to see if they operate smoothly. Take off the front wheels and drums and inspect the brakes. Also inspect the rubber hoses to the brakes and consider replacing them if they are 40 years old. Might as well repack the bearings while you are in there.
Then give it a grease job. Probably there are plugs in most of the grease holes, take them off, put in a zerk and fill till you see grease oozing out somewhere. There is grease hole on the center link that is tough to get at with the gun, you will need a 90 degree zerk for that one.
Also, look at the studs holding the exhaust pipes to the manifold, maybe they need tightening. See if you have a H-pipe and if you don't, and you want to upgrade your V8 sound system, make plans to get one.
Look at your transmission pan and figure out what kind of transmission you have so you can ask questions here when it starts giving you trouble. Remember to find and grease the U-joints.
Just a few ideas, hope they are appropriate to you and your car.
