New to me 69' C20 Suburban

[ranger danger]

Hello all, Ranger Danger here. Im new to the forum and I hope to be of value here and look forward to the help I will be needing. I will be picking up my 69' C20 on Friday and driving it home. It's in south central Washington and I live in NorCal (Vacaville, 700 miles). As for some of the good stuff, its got a crate 454 with electronic ignition and Turbo 400 both with less than 500 miles on them. Its got Yukon interior, fresh paint, new tires and wheels, all new brakes, new exhaust, new fuel tank, lines and electronic fuel pump, tinted windows, hidden towing hitch and more stuff I can't remember. I intend to use it for a daily driver as well as camping and towing my custom Jeep to and from the mountains. Its been lowered but I intend to put it back to stock ride height and add air assist. It has no A/C but that will also change before summer!! I'd like to put Vintage air front and rear. I have an idea about putting one of vintage air's trunk mount systems in the top of the rear of the truck. I am uploading a few pics but I have a question about one pic. It shows the coil spring which looks to me like its almost completely worthless in its current state. Am I wrong? Thank all, Ranger

Let me spend a little more time on the pics.
