Drive dog chains are assembled with alternating universal inside attachment links and outside sidebars and riveted pin connections. The universal inside attachment links have full size end sections and central sections of reduced height. Filler attachments are attached with machine screws to the central sections. Upper surfaces of the filler attachments are level with upper surfaces of the end sections and upper surfaces of the outside sidebars. Filler attachments are removed from selected ones of the center sections and replaced with pusher attachments secured at an end of each selected center section. A drive dog chain is manufactured and stored in uniform strands. Upon ordering, the pusher attachments replace the filler attachments at selected spacings on the chain.
