Hey guys I wana button up the rear end this weekend looking for a local parts store like auto zone or something like that. I need the numbers for the oil seal that goes behind the drum to hold the bearing. It's 1955 f250 with a dana 60.

 

Edit: is this a stock rear axle, or from something newer?

This appears to be the part?
