In your pic I assume the 'open' barrel end facing the camera is the end that goes on the speedo & the opp. end w/male threads, the nut on the cable end attaches to it. Looks very similar to a standard S-W adapt. Looks like it splits in the middle for gear changes & has some extra threaded holes on top & bott. to mount the vac. can & linkage. Clean it up & take some pics of the other sides please. Doug
