don't think so...the Taco springs are longer, IIRC.
Are his Taco leaves 2 leaf or 3 leaf packs? Toyota redesigned the leaf springs to include a 3rd leaf due to broken 2leaf packs. If you go searchin for new springs, try to get the 3 leaf spring packs. They're cheap at a salvage yard or from someone with a lifted Tacoma.
