pic to follow these go directly under the cylinders and are not the really rare expensive under thermostat ones .. £10 plus post
I was all excited for a minute there. It the really rare, under thermostat etc. ones I am after. Oil filter side as I have the thermostat side. Never mind eh. I am thinking of having a go at fabricating the bit I need. I am no metalworker so it won't be pretty, but it is under the engine after all.
I am sure Franks Westie spares [Walton on Naze area ] have these rarer bits you are considering making .
