They whole setup would be great, I am upgrading my wifes 65 Dart Wagon to front discs and would like to do the rears as well. Where are you in OK? I grew up in Lawton
I’ll be pulling the blown up 7 1/4 rear from my 70 duster in the next week, has what I assume are 10” brakes(flared drums). Not sure of the condition but if you take the whole rear you can have them. I’m north of you.
