Re: 81 K20 Ignition key tumbler broke

OK.... I pulled the steering wheel, Turn signal parts and then the key tumbler, but it appears something else is broken down inside the column

The auto column shifter wont unlock and key just turns loose like something broke down inside. The steering wheel unlocks so you can turn that though

I have a crappy Haynes manual that doesnt say much kinda worthless

(The rack appears to be coming all the way forward and the steering lock releases)( but auto column shifter stays locked and cant move out of park



Any Ideas or linkes

Re: 81 K20 Ignition key tumbler broke

This is a 81 K20 silverado and a tilt column

I found this picture . I did not put that red arrow but seems maybe something around there broke?

P.S. Matter a fact shining a flashlight into the tilt part of my column, I can ses loose broke piece. I thing that part at the red arrow broke , a piece is broke off , maybe that loop part?

Can I get these parts anywhere?

Re: 81 K20 Ignition key tumbler broke

Classic Parts has a kit that includes that broken part. Other vendors likely have it also, that's just the first one I checked. Oh rats, I just saw it's out of stock but someone else might have it. At least you know there's a kit being made for it. Classic's p/n is 53-571.... link to page: https://www.classicparts.com/1978-91...info/53%2D571/. Pic of kit:

I just finished putting back together. Local auto parts had a Dorman kit and I got the Lisle #19940 pivot pin puller at there also

Excellent -- I didn't even think about parts houses having stuff like that. Good deal!

I've used the Dorman kits a few times. They're definitely a life saver.
