72 K10 help front suspension

[Nitis]

The old girls has always had some creekity pop but hey she is 43 years old and all but the other day when I wanted to turn right and she didn't I had to pucker a bit. now don't fret it wasn't as bad as it sounds but it felt like the steering box hit a flat spot then skipped and continued.

Anyway took it out and had pops help me look it over and low and behold the front spring perches are loos and the rivets are moving so I parked her.

Shouldn't be a huge deal bust out the rivets pop in some grade 8 bolts and away I go. But since I am going to be in there I may as well do some needed upgrades

First thing first since I am taking it apart anyway is there any place to get new spring perches? I am sure the old ones are fine but new is better right? Especially if we are only talking like $40

Next thing is the front core support mounts are totally shot no big deal order a kit and replace them was going to do it anyway when I tore it down for paint and body work

Then I need to just replace the steering box. My understanding is 78+ have a quicker ratio. Is it a straight swap?

Then finally whats you alls take on springs. I really like the stance I have now aside from it being uneven. I don't want it to be any higher. I Am running 32x11.50s and could see 33s maybe but only 9.5 or 10.5 wide or maybe eventually go to 16s and 285/75s. Are the stock springs typically re-archabe? Should I consider them scrap? And what would you opt for if you wanted a stockish height ride?

Also since you have a general idea of the section I will be deep into what else should I give attention to? This is all stuff I knew I Was going to have to do just not in this order dang it.
