I have a 1974 Corvete coupe, the turn signals wouldn't cancel unless you turned the wheel extremely far. I thought it might be a worn out cam, but it looks ok, I did notice that it can go in two ways, 180 degrees around, how do I know if it's in the proper location? where can I find a good assembly drawing showing how to put the cam in, also the proper way to assemble the horn contacter, my horn has never worked right, I think it was put together wrong at the paint shop. thanx.

 

Sounds like it isn't assembled correctly, here is everything you'll ever need.

I looked through all the pages in the link above and can't find a good detailed view to follow to put it together correctly. I need something an idiot can follow, lol.

 

Here is a procedure I copied and pasted from Jim's site, Hope it helps.

Reassembly - Horn Contact, Shaft Lock, and C-clip
Place the upper bearing preload spring #5, the horn contact carrier #4, and the lock plate #3 onto the upper end of the shaft. Note, the steering shaft yoke #44 has two flats on opposite sides of the open end. The flats are not equal in length (See Fig. 2 - short flat pictured, long flat is on the opposite side of shaft.) Assemble the horn contact carrier so that its flat matches the long flat on the shaft yoke assy. Also, the hub on the shaft lock plate is raised on one side. The raised section should be pointing toward you as the shaft lock plate is assembled on the shaft yoke.

Reinstall the locking rod #40 and the “star” screw/set screw. Telescope the upper shaft #41 inward so that the bridge tool can be installed. There must still be some exposed flat on the upper shaft. Tighten the “star” screw with a phillips screwdriver (or the set screw with an allen wrench) to lock the shaft in place. Now compress the shaft lock with the special bridge tool or by hand. Install the C-clip with the wider leg of the clip on the keyway side of the steering shaft yoke (See Fig 3 above.)

A Note of Caution: The c-clip is a critical safety part. If it is omitted or not engaged properly, the entire steering wheel and the upper steering shaft will be able to be pulled right out of the steering column at any time.

Reassembly C-clip Retainer, Bumper, and Spacers
Now, remove the “star” screw/set screw so that you can install the c-clip plastic retainer #1 with the single tab opposite the small lobe on the carrier #4. Snap the retainer over the C-clip and install the bumper and spacers.

Note some people omit the bumper and spacers. This will allow the column to telescope forward another ¼ inch or so. You will hear a metallic clunk at the end of travel.
Reassembly – Steering Wheel and Horn Contacts
Align the markings on the steering shaft and steering wheel hub. Reassemble the steering wheel, steering wheel hub and lower horn contact assembly to the steering shaft. Make sure that the end of the coil spring sits squarely on the horn contact carrier assembly that is sticking through the shaft lock. (If the coil spring is cocked and touches any metal part of your column, your horn will blow continuously). Assemble the steering nut and torque to 30 ft-lbs. Reattach the retainer clip if so equipped.

 

Here is a picture of the "short flat".

Thanx, that's exactly what I needed.....and why my horn would constanlty blow, the "C" clip retainer was dried out and in a a few pieces with some of it missing.
