Any visual way to tell if my 67 SS/RS car has metallic brake option

[67jeffreyt]

My car is 4 wheel drum brake, was manual brakes originally but has a 1969 power brake booster installed.  My car is factory AC car and does not have the brake valve on the frame with no signs it ever had it. I don't have the protecto plate, so I am curious if there's any obvious signs if the metallic brakes were optioned on my car?  All my brake drums are smooth. I've read all the information about the brakes on this site, I just didn't know any obvious signs.

What is the code on the rear end housing tube?...Joe

I'll have look, it's a factory 3.55 12 bolt posi, from having the cover off, but I haven't looked at the numbers on the tube. It has the round rod traction bar.

Check the tube and let us know.

The ring gear and pinion are dated 67 factory gears , but code states 3.31

Well at least I know now no metallic brakes, somebody has done some gear posi swap too obviously
