Found out the hard way that T2 2.7L fits 3L but does not protrude quite so much. (3L bonnet sticks out more?).Not glaringly obvious unless you're very fussy. So if you fit a 3L to a 2.7L it will stick out about 1/2".
Keep your eye on e-bay, they seen to be like buses: several at the same time or none at all LOL. Some silly prices asked, took me 2 years to get one for a sensible amount.
