1969 Dart GTS Passenger Side Bucket Seat Latch Knob

I found this on the shelf but not sure if it's the same and it also could be the same side as yours.
Do they attach with a set screw?
I don't see anything on mine

Thanks, that looks like the same one I have - it looks to be universal - either side. I don't see a set screw in my drivers side knob, I believe it may be a pressed-in fit.

Do you have a price in mind - and my guess is shipping from North of the border will be prohibitive?
