Did you get the Koni 'Classic' adjustable shocks?

I have a pair on the back of my '62 Chrysler NewYorker which I bought used.

Do recall there was something with the bushings indeed.
I think I was able to push out liners and replace the bushings with regular ones that fit without issues. No machining was involved.

Their length was OK in recall.

Koni is a Dutch manufacturer of shocks and they are fairly local to me.
