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.
It would help if you told us what your working on.

Was just thinking about it. Not sold on getting a cover for sure though. Yea it’s a hex drain on the underside. I have the shop manual and it looks stock but I don’t see that drain plug in any of the pics from the manual so I wasn’t sure. Is there a specific name for this diff to find out more info. Probably a stupid question, but I have only really worked newer vehicles before this truck.
Hey guys, thank you for the responses. I think what I am trying to ask is if this is the stock '58 rear end? Also, is there a way to identify it when I am searching online for parts? For example if I am searching for a cover for a 8.2 GM 10 bolt I will get exactly that, or a Ford 9. But I am not sure what to type in when looking for this rear end.
I just did my ‘52 3100 with the stock torque tube,. It looks just like yours, and I just loosened the bolts and pried the cover back on the bottom to let it drain. I reinstalled with a new gasket and used anti-seeze on the cover bolts. No leaks.

If you do infact have a drain plug at the bottom of the diff, be sure to think about the plug when you use a floorjack on the diff. Later today I will show a pic of what I use along with the floor jack when it comes jacking up the backside.
