I had to replace the turn signal switch out of my '68 Vette. Didn't know what I was doing. Still ain't back together.GM/Saginaw column rebuilding used to almost be a business of it's own. The average mechanic would tear them up or put them together wrong.
When I worked a Frank Kent Cadillac in the mid 90's.....I was THE column guy. Wasn't unusual to do 8-9 column repairs a day, Not just Cadillacs, But all GM brands & quite a few AMC/Jeep products.
Theft repair where they beat the cover up with a hammer to expose the key switch rack & ignition switch actuation rod was a big money maker as it was insurance pay.
Tightening up loose Tilt columns was also quite common, Most mechanics at the time didn't have the E-Torx socket to service the 4 tilt base bolts. And the Pin/Bushing puller was never in the tool room....I have a Snap-on one & a Kent Moore one I bought through the dealer.
I preferred OTC lock plate & steering wheel puller tools over the Kent Moar ore stuff.
Your post just brought up those memories.....I rarely repair a GM/Saginaw column anymore.
Also had issues with the rear harness for the brake lights. I replaced most of the factory harnesses. Car ran a lot better!
