The funds just aren't there for full suspension upgrade, and won't be for awhile, so I ordered 4 new AALs. I've got a trailer that kills my existing springs, some of you have seen how bad my springs are. I'm going to supplement them with an airbag kit of some kind; found one for and '85 Toyota pick-up for $225. Total for new u-bolts, AAL, and bags=$360. I'll post pics of the difference with and without trailer later.
