I was told to go for the smallest one, which makes it easier to get in and that was the crossland 547 which is off a DAF apparantly.(and thats what steve heath recomends) The motor factors got it in for me
my motor factor got me a Bosch filter which is large diameter but flat and was very easy to fit. Can't remember the part number but I'll have a look tomorrow.
If you ask for an oil filter for a 2.3 cortina with power stearing, you will get the right filter for the ford v6 and it will fit between the chassis and the engine. You may need to find an assistant who's achne has heeled though.
