Hi guys, this is a bit of a daft one but my OCD is killing me 
The engine cover on the TD6 engine has a grommet which a pin on the cover clips into but I can't seem to buy one any more. Every where I try they come back as discontinued/unavailable.
Mine has gone missing before my ownership and I want one. Does anyone have one they could measure the internal diameter where the pin goes in please just so I can order/make something that'll work please?
