That will be option 2 if I can't get an original set, probably out of stainless (have some 22.5 mm OD) will have to get measurements as I don't have the old ones to compare.
Handle bars not required now No time or space to play with it at present
If this is of any use to anyone let me know I am pretty sure the viliers engine is not australian made for a Pace As it doesn't have an X on the engine number and has a push and turn kill switch not a toggle and the engine cover is green where all the others pics I have seen are red.
