Update, I have reached out to DodgeDifferent2 Forum Member, in hope to give buisness to a fellow A Body owner ,& Machinist. The key reason is from a quote I read from him, looking through the site.
"They come as a two piece unit so they can be adjusted for the A body axle flange or the regular flange. The one piece unit is not adjustable so it cannot be adapted.
As far as i knew Dr diff still uses the green bearings and it's two piece, but I stopped watching most brake threads."
Wish me luck. Still have to measure my A axles and will hopefully get that tonight.
