Can anyone tell me what brakes I have here. Does it look oem or out of something else ? I don’t see any #s on it





it’s got a Posi 10 bolt rear 3.73 gears reading past build sheet from couple owners ago

is it normal when I grab the tire for the it to have a bit of in out play ?
Looks like the axel moves a bit not much in and out ? Not sure if it’s normal on these

 

The suspension is not OEM but the brake drums are. They used aluminum drums with steel inserts on some years of the G body. John
