Swapping springs from a 74 K20 to a 70 K20? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Just picked up a parts truck (for axles) and it looks like the springs will swap over. Anyone ever swapped springs from a 74 to a 70? Main reason I want to do the swap is because the 747 has four inch lift springs. Help?

I don't know if they are a direct swap or not. You might check the manufacturer of the lift kit to see if the part numbers are the same for both years.
