Cruisin' on my Bluebird
I am aware of the aviation shifter hub. I have a couple sets but thank you for offering clarity to my remarks especially the years of application. Good stuff! The OP mentioned he has a SA shifter on the bars currently, so my suggestion was that SA didn’t offer a manual 2 speed shifter that Schwinn equipped the corvette with in 58.Bendix had two different actuated 2sps. The first one, the bendix aviation is manually shifted with coaster brake. I believe it was available 54-59. The second (kickback) was available 60-69 with updates in 65.
