Topic: 1969 Rear drum blackout

[ASSET90]

Does anyone have photos of 69 rear drums so I can see the brushed on blackout? Any help will be appreciated. Thanks

Here is a reproduced effort






Here is an original (67 example) the rust shows up as orange - must have been the camera settings

Oh you can have it if you want it We're here for help and support

As a NOTE - The blackout appears to be dependent on what wheels were ordered - typically styled steel wheels received this in 69.

Thanks Jeff, That is exactly what I was looking for!

The sloppy application of the blackout looks good....on this one I did a few years ago it was probably not sloppy enough.  You also could/should machine the edge of the drum and the groove if you want it to look correct.  The edge of the drum especially stands out nice when looking on the underside when everything is assembled again.

As Marcus relates the blackout is too nice compared to assemblyline however the The groove detail and edge detail is spot on. Nice job!

Was this same blackout  also done in 1970?  (car is a May 70 Dearborn build Boss 2)

Guess we should have made it clear from the beginning

The blackout appears to be dependent on what wheels were ordered - typically styled steel wheels received this. Which for you (70 owner) would mean (as I understand it) magnums

Thank you.. makes perfect sense.

Whats interesting to me is that those features are not always machined. You will find drums that the groove is actually cast into the drum. Those also seem to have a cast non machined edge as well

OK which two and were rear axles assemblies shiped with ot without brake drums?

[specialed]

The whole rear assembly was all together with drums on & green clips holding them & orange plastic holder keeping brake cables together on complete assembly. On the Dearborn cars I worked on I have seen KH on 1 side & bendix on other & hardware different on brake cylinders between the 2 with flat bolts on 1 & sunken head bolts on the other & both have different ink stamps date type marks & both types rubber adjusting plugs. I see more drums without extra hole type than other version on Dearborn cars.  Also later they started stamping date on bottom outside backing plates in the metal.

What was the purpose of machining the edge after the blackout application and what was the function of the groove?
