Would assume that since the backing plates come with the axle that the Pontiac Backing plates would also be natural steel. This is how i have always done them and now i wonder about drums.
Also not to get too deep but would the 12-bolt chevy axles installed on 1970 Trans Ams and 1970-1972 GTOs be painted ALL BLACK?

This is a '69 Firebird at Lordstown. Appears the backing plates are not coated. There must have been a paint process in final assembly to coat the axle and exhaust system.

A freind and I were just discussing this the other day. Would appear on this car the black was sprayed after , coating the ends of the exhaust when hap hazardous eating from behind? As per the assembly manual the area around the brake drum ti backing plate is not supposed to get any paint in it so they stopped around the bolt in flange . Axles ends should be free of paint. This is my understanding anyway

Some other pictures I had in files
This was the blue 69 vert bird much as described which is how I’d have done it at one time myself. It’s a nice clean look but maybe not correct. I also like to see the welds made to look like a welded/ heated color if it’s supposed to look like natural steel, Looks really good but again maybe not correct.

That's correct for a Firebird, not a Camaro.
Camaro axles, backing plates and drums were painted by the axle plant. There are several other vintage road test pics that show this.

Top pic is unrestored bird has black backing plates all the way out where the red one has unpainted but over sprayed backing plates. Assembly manual shows that joint from backing plate to drum should be clear of paint and over spray . But that unrestored bird rear looks an awful lot like how the Camaro diff looks . Differnt plants? Maybe I could look at date and plant of that particular unrestored firebird Lordstown 11C Last edited by turbo69bird; 12-18-2022 at 04:22 AM.
