Looking for a couple plugs for the hydraulic pump

I managed to strip two of the plugs on the hydraulic pump while attempting to add fluid.
It's the top fill plug and the plug next to the relief valve - I think it's called a dummy plug.
See photo.

They don't appear to be standard bolts so I'm hoping someone has the part numbers and/or knows where to buy New Old Stock.

I reached out to Top Hydraulics since they seem to be the experts and they recommended cutting a slot in them so I can use a flathead screwdriver, but if possible, I'd rather replace them.

Klaus @ Top Hydraulics is the man
Surprising that he doesn't have or know where to obtain replacement.

To clarify, I managed to extract the plugs but now the heads are stripped out so I want to replace them.
I keep an eye on the U Pull yards near me and I've never seen them list an SLK.

If you have access to some one who has a tap and die set and a caliper, there will be a measuring tool that will allow you to measure the thread pitch (TPI) and then the diameter.

AND knowing the length of the ones you have, you may be able to source new ones that way.

How did you make out?
I work on hydraulic systems and there a few different options for the rounded out center hex. There are external stripped nut sockets. I have the Snap on set that almost always work and after so many uses they do dull.. full warranty, get a new socket. The other option without these sockets are a sharp chisel place 90° like it's a racket placement and hit with hammer..

I would never drill and risk getting the shavings in the system or hitting internal components.

Once out bring to any hydraulic shop that makes hoses or services hydraulics.. they can get these or would most likely have them in stock
Cat dealership would be the type of shop I'm speaking of.
