Wow.....Elvis lives in Sherman. You don't happen to make down through Little Elm every now and then do you?
I haven't used this kit, but it sounds like a fair deal for everything that you get (I'm assuming a couple of things here....new upper and lower control arms, leaf springs for the back.....new sway bar(s)??....maybe a Monte Carlo bar).
Any good suspension rebuild kit should come with new spring perches too. I don't know if any of them do, but I think all the original perches are trashed these days, and it's about time the suspension kits started addressing this.
So grab yourself a peanut butter and banana sandwhich and order up a new suspension for that Stang.
