1967 Cadillac turn signal switch arrived

Today another 1967 Cadillac turn signal switch arrived for my 67 Deville which is in the shop at the moment with a broken switch. I found a nice NOS switch on ebay and finally it's the correct one. All the ones I bought in the past were the wrong ones as 3 different ones were available in the 1967 models! Non of them is still in production or reproduced and they are very hard to come by. Originally they were built by AC-Delco and Boyne and they are very different as I learned later... I already spent quite a sum for wrong NOS switches. Used ones are usually sold for $250.- to $300.- at the big Cadillac parts specialists... Here is a picture of the NOS one I found - it was manufactured by Boyne.

UPDATE 2010: In the meantime (since 2009) the Boyne switches they are getting reproduced and show up on ebay all the time. Also OPGI shows them in their Cadillac catalog. Its harder to find one for a T&T column as they are not getting reproduced so far. I do not know where one could find a switch for T&T though. If you know of any resource for T&T switches please let me know, I would love to have a spare one for my Eldorado!

When I was looking for a switch for my 1967 Deville, I only investigated resources for cars without T&T columns and this is what I found out:

According to the 1971 parts manual there are two different ones for standard column cars and one for T & T

1967 - 1968 (Exc. T & T) Part # 7800483 - Switch, w/wiring harness (Delco-Remy)
1967 - 1968 (Exc. T & T) Part # 7805675 - Switch, w/wiring harness (Boyne Products)
1967 - 1968 (T &T) Part # 7805676 - Switch, w/wiring harness (Hazard warning switch an integral part)

The two different standard column switches can be identified without removal as the parts manual describes:
„Hazard warning switch is an integral part. Switches can be identified before disassembly as follows: The Delco Remy switch has a square hole for the hazard warning switch in the cover, the Boyne Products switch has a round hole for the hazard warning switch in the cover.“

The problem with the switch on my standard column DeVille was that the return cancel cam broke, and that non of the repair kits were available for the Boyne switch.

Replacing this switch in the steering column is quite a pain - below you can find the instructions from the shop manual on how to do it.
There is also a revised procedure for a much easier installation below in the “Cadillac Serviceman" from August 1967!
