Ok, here goes...on my 1954 I purchased the turn signal bucket, cancelling cam, lever / knob from classic parts and they work just fine. I went the "factory style reproduction "because I wanted the self cancelling feature after having another driver pull out in front of me because he thought I was turning onto the road he was exiting, and i had not heard or seen that I had not cancelled the turn signal from the last right turn.... I had to brake hard to keep from getting hit. I purchased the parking light/turn signal from The Filling Station and the Taillamp assemblies from Classic parts because they have the most correct pigtail I could find. Other suppliers provided a very cheap two wire cable with no good means of keeping the wires in the double contact terminals. I now have an extra set of taillight assemblies. As far as wiring, used the wiring diagram provided with Classics turn signal bucket which matches the Chevrolet Accessories Installation manual wiring instructions. And, it all works as it should.
