Black painted steel. Reproduction part. Will fit all 53-84 Big Twin models but earlier 53-E76 model OEM screws do not have the flat base screws that are required for the late model tappet blocks. A special conversion screw set is required for 53-E76 models that will fit the different threads that are used in 53-E76 crankcases. (like 502990 allen head or 513555 acorn). Repl. 18602-80A rear and 18603-80A front tappet guides. Note: 53-E76 models require a special conversion mount kit.
