This is a 53 right panhead case and a 78 shovel left case. Great set to combine a slab and a late style charging system. The right case has been repaired in the usual place above the front lifter block and above the cam bearing. Whoever welded these did a very good job. Some minor finish machining and this case set would be ready to rock and roll. Cylinders and heads not included. 4-fun cam cover is included.
