Cant wait

Thanks, here's our 67 button. There's a depth difference that would expose a lot of the innards, but it doesn't fit anyway. My retainer may be different?
Steve, here’s a pic of the Plymouth steering wheel cap from my 1967 Barracuda.

I’m not sure how the one you have attaches to the horn ring but this one just turns about an 1/8th of a turn to the left to remove it. There are three “spikes” that fit into the slots on the horn ring.
