Any idea if this casting number is possibly for a 67-69 rear brake cylinder assembly 5464077? Has the split circle but no Delco Moraine cast on the opposite side, so not sure if it's an original or aftermarket. Rubber boots on the ends read Delco Moraine. I found this in a box of parts for a car that uses 31/32 dia. rears, and never owned any other vehicle this would fit. Not sure if it came with my 67 purchased back in the 1980s.
