get the spring at a junk yard for $20 or less. most, including mine, springs with 180k will sag in the rear. so they're not really "99 tall springs" they're worn out pieces of metal.
I'd say pass also. You can buy a new set and get them in a few days. Cracked spring, I'm guessing you can limp around for a few days for new springs to ship. I see you're looking ahead to a 3" lift anyway. Looks like a good excuse to get it!
Haha! Yeah that's the excuse I gave the wife for "needing" the lift. Yeah I'm just gonna limp it for a few days. I don't drive hard or really that far to/from work so screw it. Thanks guys!!!
