you can have the old stock springs off the back of my 89 runner if you want. I would use this as a chanch to put chevy 63 inch spring on though if I were you. It will ride so much smoother and flex alot more too. Here is what the Chevies look like next to the stockers.
Check out this link for great info. I dont think the aftermarket makes a better spring then this for your runner.
...and I would get the MT's
