Suspension and frame work, cracked LCA, advice welcome

Another issue would be the ball joint and tie rod end boots, they are all shot but the ball joints are pretty tight in like new condition as much as feel.
All of them are sealed and do not allow greasing. I want to save them and replace just the boots.
Found here at a local import a set of PU boots, supposed to be Energy Suspension brand... that would fit.

My question would be if anyone knows if these PU boots seal good, keeping dirt and water from coming in contact with the ball joint at all times when the car runs.

I have an old rubber booth I bought long ago that shows in the pic, if you turn the ball pin it will lift on one side and that would not be acceptable as far as sealing... Are the PU boots sealing any better at all times? The stock ones have a metal ring that will keep it in place.
Added a few pics...

Remember, when part is installed boot is pressed down over socket. In my opinion you are overthinking it. Likely the ones you have will work.
