Do you got a tilt steering column?

Not much infos on regular column.....hope this help.........

I think I figured it out, the above pics were a big help.

The pic below shows the Chevy 4 speed part on the left and the Pontiac powerglide part on the right, you can see on the inside and outside they are identical, just no mount for the shifter or hole for it in the 4 speed part.

That pipe sitting on the left part fits into the 4 speed part (on top, right where it is touching) and then the top part with the plastic signal light and horn piece fits on top of the pipe. The bottom of the 4 speed part slides on top on a pipe inside the steering column. As far as I can tell, it is just friction from the 2 pipes that keeps the 4 speed part from moving, I'll find out once I get it back together completely.

On both these parts, you can see a rectangular groove on the left. On the column shifts, the pipe inside the steering column is longer and it has a rectangle on it that this part slides on over. I saw they were shorter and I wondered if I had lost a part from the 4 speed column. There is also a problem with the reproduction plastic signal light part that was confusing me.

Never throw old parts out, until you have the new part working. If you look at the pics of the 2 plastic pieces, you will see a ridge of plastic on the new part that is not on the old part. Both the Pontiac and Chev old parts did not have that ridge. The ridge will not allow the plastic piece to slide on over the pipe on the 4 speed shifter part.

That top metal piece which fits next to the steering wheel, it was stamped with the same GM part number on the 4 speed Chev column and on the Pontiac Powerglide column. The only difference in the 2 was the PG piece had screw holes to mount the PRNDL, plus it had a hole and mounting hole for the light.
