attached is a list of the Water hose (and clamps and such) part numbers AND if its still available from Mazda, today.
actually the stuff they have, they have lots of, and a couple parts, like the heater grommets have been brought back.
i grouped it 79-82, which is the same, 83-85 12A which has the tall radiator and beehive oil cooler and the GSL-SE which is a different engine :P
