For the gotta be original crowd the oem part number for the 1970 a-body disc brake master cylinder is 2229171 (I think). Those are hard to get, and the prices can be absurdly high.

Could have been a mistake from factory. Made into a race car and was the best stoping car I ever owned. Original has a strap over the top where he bolt goes thru. Every power disc brake one I have seen has the one on the right.
