Since you have it this far, I'd at least pop the bearings out and see what they look like for wear. Could be just fine! Clean, add new grease and reassemble.
As for taking the rest of the bits off.....unless you are replacing the rotor, it would seem like your fasteners are still doing their job! Impact tools are likely in order................gently!!!! Machinist on standby!!
Ball joints: Do a search on this site for references of good "no mod's required" pieces. I know I've seen the posts.....and guys have found the good ones....and they reference the "where" they go on the other cars that use them. I just can't recall and didn't write it in my parts book! Duh! Goose uses same joint upper and lower according to my notes.
Sway bar bushings.... Try search also. But I think whatever you can find in the aftermarket for the size bar you have may need to do..... Could be a Fiat/Alpha part......?? (Book page 7 lists it as FIat 1300 pieces)
Sway bar end link bushings: Sleeved rubber bushings similar to shock bushings. If what you have is still good.....be happy!!! Hunt for steel sleeved bushings could be unicorns....but I know guys have found such bushings......in the size you need??? Your mileage may vary. Slim chance the vendors like Wilkensen and perhaps Stock at PCC could have them...
Shock bushings: There are some new ones floating around out there but they are crap. Soft gummy rubber that the steel insert pushes right thru and in 6 months they look as bad as what you probably already have! These are steel sleeved versions..... Again, search on this item as a topic as guys have cut new ones out of more modern stiffer rubber and pushed them into place.
Shock damper: Carello sells some....I cut in half...used small section...other shock providers likely do as well.
I was lucky as my car didn't need everything here.....shock bushings were worst...had metal on metal! Of course shocks were toast also! Different subject.....
Search on grasshopper!!! You're getting there!
