Radiator hoses question

[Bronzedodge]

Anyone happen to know the part #'s for big block with A/C radiator hoses?  The description for the upper hose on RockAuto is a little vague.  Anyone happen to know of where to get the spring for the lower hose?

Buy the one for a small block, longer than the big block.
