The flanges that Determined posted look lie 930 flanges up to 84 and will not accept axles that use the tin caps.
reddogmotrsprts, before you buy 930 axles, check the outer flange. I'm not sure the 930 axles will bolt to 911 outer drive flanges, unless you have 930 trailing arms. If you are looking to get stronger axles (108 mm CV) I've used the 85.5-86 axles. These have the outer flange sealed to the axle. They hold up really well. I have a 300+ hp 3.6 in my car with these axles
Here is the Porsche tech bulletin. Determined's 930 flanges are on the left. The 85.5 flanges are the same as the later 930 in the center. You can see that early 930 hubs do not have as big a cavity as the middle one, to make room for the tin cap.
