I have a 2010 Ram 2500 XLT. The rear differential cover is rusted and leaking. I ordered a replacement from Amazon only to find put it does not fit. Wven though it was supposed to. I looked the part up at Autozone and the picture looks the same as the the Amazon part. I called the dealer with the vin and they said it does not give them the size. How do I find out? Edit: Well I posted that I found it. The bolt pattern is for a 10.5 inch differential. I found it at Oriellys but they cannot get the part.
