jrhendo Hi,Can someone confirm that the Welch plugs on the right side of a B21/B23 are 45mm, not some imperial measurement?Also, they look like they are the cup sort- like a bottle cap. Is this correct?RegardsJohn
jamesinc I think they change back and forth between the dome style and cup style plugs, but 45mm is correct, at least for the dome-type plugs (Volvo p/n 463904). I've actually never owned a redblock with the other style plug so can't comment on them.
