Interior colour

The interior of my 71 Duster was originally all blue, at some point in time the bucket seats got lost and it had an ugly as sin houndstooth bench put in it.

I got a set of buckets from a 73' Duster in black that where pretty mint. I also picked up a console as my car was a bucket seats column shift car.

The question is now I need to re-do the seats as they are starting to crack, I just got new door panals in blue and was having thoughts on what to do with the seats. As I read it there are only black white and bright orange as colour options for seats in 71'

Also is it possible to put 71' style seat covers on a 73' seat?
