I have a pretty good leak in the old RTV in the rear diff cover. I am thinking about painting the rear end while I have the cover off, and possibly getting a new diff cover. Can anyone help me identify the rear end. I think it is stock, but I am not sure if they had a drain plug in the bottom like this one or maybe it was added by someone along the line. Kind of hard to see the drain plug I am talking about in the pics. Just not sure what to search to find a cover that will fit. Thank you.

Forgot to mention that it's in a 1958 Chevy 3200.
