Late model '75 750 GT's have a black bucket & chrome ring. The bucket is stamped Aprilia 19888, rim is stamped Aprilia 40821. The rim is 2 inches wide and they take this special hard rubber gasket for the two to fit together correctly.
NOTE: The earlier GT's with the chrome buckets are stamped 40852, are 1 5/8ths wide, and there is no gasket between the headlight rim and the bucket... Don't confuse the two types.
This fits other applications as well...
