Original OEM ATE unit. This is THE cylinder, just purchased directly from Steyr's supplier. These are new manufacture, not NOS. You may want to consider the cost of the rebuild kit, as these are not that much more expensive. Includes the rubber "seals" to install your reservoir.
Stunningly New vs the 50 Year Old One
Can hardly believe that parts are still available for a 50+ year old vehicle at such a reasonable price. In Stock, Fast shipping and direct replacement... NICE!
