Bet you didn't know what these were for! Here's a new reproduction of the front plug for the "ski rack". That's right, 914's had a ski rack option. A tongue slipped in these sockets and the back went over the roof and wrapped around under the Targa bar. Have a look... stick your head up under the Targa bar (above the engine lid) and you'll see the other mounts. Learnt sumptin new every day!
These install at the top of the windscreen under the main Targa seal. There are 2 slots that these slide into, one on each side.
Used for all 914 model years, 2 required per car.
