Come to think of it, I'd love to change the yokes in my Cherokee while
I'm at it. Get some newer models instead of these original bow-tie
yokes. And I guess same question would apply -- would they let me
take from one certified model to another???

I don't know about the seats. But the old bowtie yokes can indeed
be replaced by the new rams horn yokes. Look at the control wheel
AD that applies to the bow-tie yokes. Notice that a terminating action
is to replace them with the rams horn yokes. (I recently did that to
my cherokee 140).
