I finally managed to get the rear brake drum off of my truck but I have no idea what I have. I know the diff is a Dana 60 of unknown origin. The drum is an 8 lug drum and the brake appears to have a parking brake provision. This surprised me as I understood this was the Achilles heel of the Dana 60 conversion. So now I need parts and I need to figure out how to take it apart but what do I have here. Can you tell the vintage by just looking at it?

 

I have no way to tell what you have but it is newer. I see self adjusters there too. brakes do look thin, undo the self adjuster stuff then remove the springs that hold it to backing plate. The shoes will want to fold in but that helps to undo the return springs. At least that's what Id do.

 

From your previous pictures showing it together, I'd say it is a '64 - '69
