thanks for your reply not familiar yet with the lucas id numbers but if the spots are rear mounted then the lense profile will be slimmer front to back than post mounted ones and 146mm diameter which i forgot to mention, am just about to take out the engine (for the second time ) as having just replaced the clutch etc drove around 60km and the original fork has broken one of the thrust bearing feet ,still as they say practice makes perfect (ho ho)
