my original dip stick looks like a rat has had a chew on it i went on flea bay and found a cap that said it would fit its a m27x3 alloy cap only thing its $60 bucks Australian so i looked up a m27x3 oil filler cap as a generic cap and found one for $50 bucks waited for a month to be delivered from the USA and low and behold it doesn't fit its way to small . can some one please tell me what size its meant to be and does anyone know where i can get one the correct size . man another $50 wasted not happy thanks triumph68
