Any experience with front end "steering and suspension kits" for older cars?

Does anyone here have experience with Front Steering and Suspension kits for older cars? [1]

I’m helping a friend get a 1966 Mustang he inherited back up and running. The body is in nice condition. He’s looking at it as something to drive around locally, and not as a daily driver or for long trips.

We got it running and it’s now registered. His front suspension is sloppy and loose, and has more steering play than it should, (even after tightening the steering box adj screw).

The car is 1.5 hrs away from me, and we’re doing the work on his garage floor. We work on the car about twice a year. Hence I’d like to optimize what we can accomplish each time I’m there.

I noticed his lower ball joints have excessive play. I didn’t give it a thorough front end check, but am thinking that other components must be worn as well.

I could order just the ball joints, but my fear is that we’ll find other items needing replacement once we we’re in there. Then I noticed various kits like these [1] are available. They may be an overkill, but it would be nice to get everything done all at once.

Does anyone have any experience with kits like these? When I called one of the places that sell them, they said although all the parts are from China, those who buy them tend to not have problems.

If anyone has had experience with these, please share.
Thank you.

Tech Tip, if using polyurethane bushings, make sure you lube them properly or they WILL squeak, poly graphite bushings are much better as they are infused with graphite, which acts as a built-in lubricant to prevent the annoying squeaks and suspension binding that unlubricated polyurethane is notorious for…

My advise would be to check out some of the mustang forums and ask around in there…
