Rear brake drums

FYI, Around that time because of a strike from their brake vendor,Chrysler used C body rear drum brakes on some of the A bodies.They had 11x2'' brakes on the V8 cars. I got a 8 1/4'' rear from a '74 Valiant that had 'em.Some thing to watch out for.

Any proof of that happening at the factory?

I have not heard this one before.

Are there any historical links out there with information on this strike?
