For sale is a new in the box, never used Sealed Power N17782 which is a rear pinion seal for a boatload of BMWs. several Mercedes, and a few Nissans. This seal has the C/R part number 17782 on it, it crosses to a National 1979 and a 17782 C/R. This seal would not come up in above fitment listing. I did some research and this pinion seal fits about every BMW ever made. If you need to verify fitment get on the Federal Mogul web site and put the number 17782 in the cross, and go down to applications. I cleaned the box and the seal and the number on the seal matches a variation of the number on the box.  This box have been handled several times and is a little ragged, but the part inside is perfect. The key is to get a bargain on a brand name part, no matter what the box looks like. If you have any questions about the compatibility of the parts I sell and your vehicle, please feel free to contact me through eBay. Thanks for looking, Scotty.
