Original spare parts manual lists 1/2 rings as 14807 and 3/4 rings as 11379. Only ones currently available from suppliers seem to be part number 14809. Is this correct ?. Surely different part numbers mean non interchangeable - least it did when I was in the trade . Who do you recommend to supply quality parts ?
Converting the box to fit overdrive - have read that breather needs to be blanked off on top cover , is this correct ?
