I'm trying to pick up a couple pairs of stock leaf springs to do the leaf pack rebuild for my taco. I've got a line on a pair from an 03 and a pair from a 96. I'm wondering if the ones from the 96 will be correct for the rebuild. I do not know if it's a 4x4, 2wd or what. I have inquired with the seller for additional information but have got no answer yet. Are there any differences in leaf springs over the various years and models?
