mk1 1.6 gti engine dipstick query

i`ve just noticed that the dipstick tube on the golf is missing.i haven`t used it for about a year and the last time was from the mot station.its either gone missing or has been nicked?? but now i can`t check the oil.anyone got a picture of what i`m on about as for the life of me i can`t remember.anyone got one for sale as well??

gsf sell these for cheap, loads on ebay. just called dipstick guide tube or if you go into gsf and askim sure they'll know what you need as its a very common part to snap
