the lambretta gearbox is week point,so mix-matching gears that are not of the same diameter and pitch of gears is really not to be done,if you try this it could easily break a tooth and bust a hole in the case, much cheaper and easier to get the correct toothed cog,it does compare with several other lambretta boxes that are crap ratios and will be cheap,try an advert on here for the correct cog £10-15 should be the maximum you would be expected to pay!
