Should I keep my power steering

Do you have a part number for that master cylinder? When I look on Rock Auto, I don't see one that list the bore size and it sure sounds like I need that one. My brakes are all new, drums all the way around and the pedal is quite hard to push. Thx!

In case others want to know also:
Part number for the 15/16" bore drum / drum master cylinders.

Raybestos MC 36338
71-72 DART manual, drum/drum
15/16" bore

Works good as B body drum/drum manual master also.

Available at Rockauto, Summit, and Ebay
