Part no for this little gem is 4663870, or so it says on the MoparPartsGiant.com website and engine block diagram for a 99 300M 3.5, which is where my 3.5 came from. Part is discontinued; however, they're on ebay, found one for $64, and it supposedly fits a 99 LHS 3.5 engine, and is an OEM part. Problem is, it doesn't look like the rear crankshaft oil seal retainer I took off of my engine. In fact, the part number stamped on the rear crankshaft oil seal retainer I have is 4663871. I found one of those too, problem is its used, albeit in good shape. And 4663871 is listed as a FRONT crankshaft retainer seal on the internet, every listing has it listed as such.
Now for the best part, I thought the rubber gasket was simply a remove and replace, and started to remove some of the rubber gasket. Its quite hard, and a bit brittle, and its not coming out very easy at all, and now I know why, hooraaayyy! The rubber gasket is a permanent part of the retainer. There are rear crankshaft seal kits on ebay, but other than the rear main seal, the other gaskets don't look like they will fit on my seal retainer. Sooooooo, I have a seal retainer, with a hard and brittle rubber gasket that will be a ***** to remove, and no replacement available. I guess its remove it, and purchase some form a gasket, and glob it on! Any other suggestions guys???
