69 Z28 Camaro rear brake drums?

[rally]

Guys what style rear brake drum did Chevy use on the 69 Z28? Was it the smooth sided drum or the finned style? Also did the factory use a balance weight on there drum along with a GM stamped code or ID? Thank You

Rear brake drums were non-finned; some had a balance weight, some didn't. There should be a casting number and maximum diameter cast into the O.D. of the drum.

Thanks John for the info.
