You have a '96. Your leaf spring is old and worn. It needs to be replaced. It is not a good idea to install lift shackels with junk yard leaf springs because those are also old and worn. You may not have any problems in the sense that used springs probably won't snap or break on you. But what is the point? How are they going to improve your ride quality. You'll just go from your worn ride, to someone else's worn ride. You might even get a leaf spring pack that is in worse condition than what you already have.
If you can't afford to buy new, then save up and wait. Don't regret it later. You got new shackels. Now follow that with new parts all the way around.
While we're at it, what about your shocks? You getting used shocks too? Or the u-bolts. Are you planning on trying to fit a multi leaf spring pack under your axile with 15 year old hardware that was originally designed for a mono-leaf? These are items that have seen 15 years of stress from what? About 5000 pounds? This isn't a bumper, body panel, door skin, or window. Your car is depending on these items so that it is "suspended" off the floor. You'd rather drive down the highway at 70 MPH, then have the frame and body drop?
A lot of people will scoff, and insist on there being nothing wrong with recycling auto parts. Would you buy used brake pads or tires? Maybe I'm biased. I've seen too many junk yard parts fail after installation. Imagine changing out all your belts and hoses with junk yard parts. I don't recommend used cooling system parts either.
This isn't a necessary repair, right? Your leaf spring isn't broken? You're doing this for aesthetics and maybe performance. That's why you bought the Warrior Products instead of an OEM replacement. Get a set of Deaver Springs and some new shocks, then think about how you're going to lift the front end. This will all be very expensive. After front & rear suspension, wheels & tires, and re-gearing so that you can turn those wheels & tires efficiently; you'll be sinking $5,000 to $8,000 into a car that's 15 years old and worth less than half as much.
