Classic/Antique Car Repair: Turn Signal Switch Replacement, jeep cj 5, tilt wheels

Question
QUESTION: Brad,
I'm the orig owner of a 1976 Jeep Cj-5 (man Trans). When purchased this vehicle came with a standard column (No-tilt). Back in 79' I installed a tilt column when I found out that any GM Saginaw Steering coulumn (of that era) would swap in. Now the Turn Siganl switch needs replacement. The column has the tilt lever & the turn signal lever (No airbag). The signal lever also has the option to turn on the High Beam headlights, but I don't use this due to the foot switch in the floor. A couple questions. How can I identify the column part number so I can get the correct replacement component & can the electrical harness connection be fished through the column cover as to not take it completely apart?  I know this is a custom question, but it is pretty straight forward. Any help you can send my way & Thanks in advance.

ANSWER: According to my old parts manuals a switch from that era, 1976 through 1984, with tilt wheels should fit. The tilt uses a different switch than the non tilt. The original GM part number is 1997984. Your GM dealer should be able to run the part number and see if it still good or has been superceded. Now, when you disconnect the wiring harness at the base of the column, tie a string to the end. Then pull the switch out pulling the harness out through the top. Use the string to draw the new harness down through the column. Good luck.

QUESTION: Brad,
Can this switch be replaced while the column remains in the vehicle, & will it require a column tool to get to the switch?

Answer
As far as I can see the switch can be replaced while the column is in the car. You will need a tool to depress the switch lock plate to be able to remove and re-install the snap ring. This is not an expensive tool and can be purchased at store like NAPA.
