You need to fix the brake hose interference problem even with new lines. The easiest way to do this often to rotate the soft line in it's 6 point captive mount at the hard line. This is very easy to do. People do not think about that orientation when they tighten them up or that when the suspension compresses, they move often not the way you would expect!

Assuming they are inverted monoshocks, they need new bushings between the two housings. This is a wear item on inverteds and part of a rebuild. You will likely need to rebuild rally shocks annually if not more often. Maintenance on them will reduce that.

What pads are you using? Titanium shields and different pads might resolve fade. EBC Reds come to mind.

Fab a tank guard/skid plate and/or buy a used tank and cut the bottom/sides out of one of them and use as a basis for the skid plate reinforcing as needed.

What can you pick up a low millage motor from a wrecker for?

Any stock LSDs that will fit? Again, a wrecker will have those cheap.
