1982-1985 Alfa Romeo Spiders were equipped with 8mm wiper arms. The Bosch wiper blades we offer come with several adapters, but unfortunately, none of them were designed for Alfa Spiders. The part you’ll need is an SEV Adapter, #40009. The SEV Adapters are equipped with a shim that must be removed first. See photos below.  
 Once the shim is removed, install the SEV Adapter on the new wiper blade. You should then be able to insert the wiper arm into the SEV Adapter until it “clicks” into place. Remember to test your new wipers before your first drive in the rain just in case! |
