Bucket seat track questions

So I am trying to convert my 68 Fury from bench to buckets but I am running into a snag with the tracks. I am from the A body world so I know how Ma Mopar changed things like that over the years however I am in the dark when it comes to C bodies.

So the main things I am trying to find out

1. What years interchange for a 68? can I get 1965 or 1966 tracks and are they the same as a 68?

2. Are C-body tracks even close to 68/9 B body tracks??

3. What years were they adjustable? I have a 66...
