It's time to replace the old Signal Stat on my '54 3100, so I'm considering options.
It would be nice to have an integrated turn signal assembly instead of the clamp-on. Has anyone tried installing one of these? | | | | | Joined: Sep 2009 Posts: 5,874 Gearhead, Stovebolt Tech and Parts Tracker, Mod for Swap Meet and GTT | | Gearhead, Stovebolt Tech and Parts Tracker, Mod for Swap Meet and GTT Joined: Sep 2009 Posts: 5,874 | Crusty54, 1st off, Welcome to Stovebolt!  According to a couple different Chevrolet Master Parts Catalogs (1954 and 1957), the "turn signal assembly with cup" was offered as a standard part under Parts Group 2.895. The 1954 book indicated GM# 897334 (applied to 1954), but the later 1957 book indicated GM# 897125 (applied to 1954-55 1st Series). You might want to check this old thread concerning the turn signal assembly that is a bolt on for your truck. I recall a more recent conversation not long ago about this, but couldn't locate that particular thread. Perhaps another Bolter can point you in the right direction??? Anyhow, the above linked thread does provide additional info on things you will need beyond the noted switch assembly to install the unit your mentioned. Dan

In '57 Chevy and GMC went to a dished steering wheel and the turn signal lever followed the dish, so the part that the lever screwed into was modified to include the angle of the dish.
'57 GMC 102, Original 347 V8, HydraMatic, 3.08 rear gear, added A/C, disk front brakes, HEI, AFB carb, '98 Honda Black Currant paint. T-boned and totaled 10/12
'52 GMC 152 Stake Bed, Original 228, SM420, added A/C, HEI, disk front brakes, '67 Chev 3.55 rear gear. Gets used as a real truck.

The electronic one is impossible to forget and has added features. We use the Kawasaki motorcycle switch which one can get from a m-c junkyard for ten bucks or one can buy an engineered one from Amazon for $60. One on my 37 Buick has been trouble free for thirty years. Just google "self cancelling electronic t-s switch."
