Springs , UCA and LCA are all stock. Both GM ID stickers were 3 from the top and both were clocked so the end of the spring was right between the inward drain holes.Just opposite ends up.The car is from california and Ive had it for 18 years,never wrecked or taken apart(original factory stickers on everything) and still has rubber insulators on frame were the springs go up into.Thanks for info and conformation guys,I had to be sure.
