Lock cylinder

[70barracuda]

Anyone know if the 86-90 ignition lock cylinders work in a 91+ column? Bought a "new" tilt column and it's a 91+ with chrysler keys. I would like to use my original GM key if I can.

I don't know but it sounds like you have the parts at hand to find out for us! 😜

I kind of doubt it will be plug and play.

If memory serves, it’s a no. It has to with how it’s held into the column. The early cylinder uses a bolt to retain it, while the later cylinder uses a spring tab, which is not present on the early cylinder. 
 

I was able to make a 91+ cylinder fit into an ‘89 column by grinding a notch into the cylinder where the retainer bolt goes, and removing the spring tab. But I don’t think you could add the spring tab to the early cylinder to go the other way.
 

You can see the slot on the far right of the Chrysler cylinder, that’s where the tab was.

This reminds me of my 84 where it doesn’t have the bolt to keep it in place but it has a spring tab on the lock to keep it in place.

My Dad did this swap last night on the 91' XJ,

 he had both early, and late lock cylinders.

 

Before (Chrysler key) :

After (GM/AMC Key) :

He was surprised the 91' column took the early lock cylinder (WellsA08004)
