400 Airborne pump [2B6-26] – this can be a difficult item to locate. 35 years ago Piper issued a replacement kit p/n 760-791 to replace the original Bendix pump . If you still have the original Bendix pump and need the Airbrone and the mounting bracket, call me.
There is a 337 floating around for a replacement Dukes pump; I should be able to capture that as a solution for the non-available 2B6-26 core issue soon. This will allow installation of the replacement pump which can be purchased outright, thus bypassing the difficult issue of finding an Airborne core for exchange or overhaul.
