Bosch 1-311-015-077 (often formatted as 1 311 015 077) is a vintage Bosch manufacturer part number for a Porsche rear bumper reflector mounting base. Porsche number on the part is 901 633 010 00 which is actually the part number for the complete assembly, not just the base. The base shown here (for sale) provides the physical mounting housing and rubberized/plastic foundation for the red reflective lenses located on the rear bumper corners. It does NOT include the lense/reflector. It can be used on either side, left or right. Part for sale is packaged as "genuine Porsche", not in the Bosch box as usually sold online. It is new, old stock (NOS). Includes the 2 mounting carriage bolts (1 has some slight oxidation but threads perfectly). There's currently a new Bosch unit on Ebay for $106. (17e)
