Did 67 rear drums have self adjusters ?

Looking at the rear drums on my 67 Barracuda, they are 10 in ( I think) on a 7 1/4 axle. There are no self adjusters, did they have them as standard in 67. Does anyone have a pic of a correctly assembled set - photo or manual page. I can see where the shoes have been modified slightly to fit and re-drilled for the lower spring so need a reference to how they should be.
