I got mine from Stage3motorsports. The part number for my truck was 46-70152 It's the same for anything with the 9.75 axle. I don't think the sight glass is a weak point for a couple reasons. It's mostly protected by the axle for anything but a lateral (from the truck) impact. The sight glass is an aviation grade product, it's pretty stout and hasn't even picked up a scratch on mine yet. I'm sure it'll eventually get crazed or foggy but I can replace it should that happen in a few years.I bought this model on a whim since it seemed to have the most desirable features. The sight glass is pretty cool because you can instantly check for water intrusion after each run instead of doing some exploratory draining and filling.1997-2014 F150 aFe Rear Differential Cover (9.75") 46-70152Current price is $241.50 if you use coupon code STANG15.
