175 "type 1" extended end connections for Panda Plastics M4 Sherman series tracks. This set has enough end connections to make up the out side set of end connections for both tracks. Please refer to http://the.shadock.free.fr/sherman_minutia/tracks/vvss_end_connectors.html for the different types. The parts are sprued at the correct spacing to allow the connections to be attached to the links before sprue removal. The sprue can be used as an assembly aid.
