@MVSpyder I contacted a buddy of mine with a Spyder that has a 911 shroud and had him send me some photos of his filler. He has a FAT Performance Type IV motor so I don't know how much that will affect the placement of the oil filler. His oil fill is on the driver side of the car in front of the intake manifold for the driver side carb. The billet aluminum cap is down low and the fill tube goes directly into the valve cover. If you look at the first photo you can see the billet cap in the lower part of the triangle formed by the tubing. Not sure if yours is there also but its a place to look.
