This is the adapter that is used to connect the distributor to the head on 6-226 Super Hurricane engines. The adapter is made out aluminum and has the hole for the stud on the head to go through and the other end has 1/4-20 threads on the distributor end to adjust the timing and bolt it down. This is a nice part that is commonly broken.
