The reason I "know so much" is my use of the ANSA. Once it is on the car, the four tips ae about 1" wider, than the OEM! So the original screen won't fit...they tossed it away! I borrowed the part as a sample and the shop lost it...so, I have has the pleasant experience of buying a new one and giving it back for the loan! I had a pattern made, and then you have to find the stagger slot metal.. So any of you NON CAT owners running the ANSA, my Hot Rod Fab Shop is going to make some "replicas" that will actually fit, and hide the muffler as intended. He must be reading along as he wants "$450 each, paid in advance" to do one. Which is what an OEM unit costs, shipped from the UK! But I was going to make two (they are very likely to get damaged that low in the rear) and maybe we get him doing three or four he would back off that price. It is what it is. It would be a shame t cut up a new ANSA, to make the tips correct. Odd they would be "just a little bit of" like that...the oval trim part will be very tight to the angled corner of the shroud at the end of the day with my new ones... To recap, no 'glass car has been found with mounting holes, to my knowledge... The CAT equipped cars got the later shroud. I guess there's a lot of these "laying around" any old shop. You see one now and then on EBay...usually well worn, I've seen one that was cut in half to move the tips CLOSER together!
