got new toy, feather duster!

Congrats on the Feather Duster! I sold mine years ago, wish I had it back, been looking for one ever since.
Mine was all Drums and small bolt pattern on all four corners. I was told that Ma kept small bolt on slants till '76. Any late model 904 yoke should fit your auto if that is the question.
My OD four speed used a 904 style yoke on it. Can't help you and any pedal or swap prices. I will keep my eyes open for you.
Post some pictures of yours, here was mine:
