Hi,
Because I thought my eyes were failing, I checked this again in the Laser Catalogue, item 3117 is a 3/8 drive 76/14,........ however item 3801 is a 1/2" drive 74/14,..... then I found that the following caveat applies :-
" Before ordering it's best to try to measure the oil filter and count the number of flutes on the cap, as even the same model of car with the same engine can be fitted with different oil filters during its production run."
So the answer is, to physically measure your cap, as one of 2 sizes cap may be fitted.
