Smile Shifter maintenance and u-joint

I've only ever worked on suspension and tires so haven't read up much on transmission maintenance. But looking at the car from underneath I noticed some concerning things.

pics of Shifter and u-joints: https://imgur.com/gallery/GzKfFtD

What can I do to clean up and maintain the shifter there? looks like boot is off and fluid coming out.

Also I have a tough time shifting into reverse and heard it's the U-joints. Are these the U-joints I can easily swap out?

Also a suspension question about my pic of the upper control arm. I got new torsion bars coming and want to crank them up a bit. Can I do that w/out having to get different UCA? Don't want ball joint angle to be bad.

If the boot is ripped, replace it. If it's not ripped, slide it back down onto the housing. Re-clamp it if necessary.

Those u-joints won't prevent shifting into reverse. Question; Would you say there is allot of slop in your shifter? Because if the nylon bushing that belongs on the inside has fallen off, the shifter will have to move much farther to shift into each gear. If that's the case, it may be hitting the edge of the floor opening before it fully engages reverse. That extra movement would also explain why the boot is pulling away.
If that's the problem, it is a cheap part, and pretty easy to replace. It's a matter of removing the inner boot, unbolting the shifter (flange and all) and lifting it out. Pop a new nylon bushing on the tip of the shifter, and put it back together.

I can't answer your UCA question. I'm only familliar with the 4x4 version, which has different UCAs.
