Help with these bleeder screws

So I’m getting ready to pull my demon out of the garage, but wanted to bleed the brakes first as it’s a new car to me and I haven’t gotten my hands on them yet. I got the rear just to eye them up and this is what I found on both sides. I feel as though there should be a screw there, not nubs. Any input on what these might be? Car had a previous life as a strip car. Thanks

Hello Markzilla88,
Hard to tell from the photos and or all the accumulation of stuff covering it.
Yes there should be traditional type bleeders installed.
Could be there were rounded off wile someone was attempting to work on them at some point, Or they were removed and a plug (Hex) of some kind was installed.
Any way agreeing with Justme it probably would take more time and effort to try to remove them and install correct bleeders, If you even can seeing that there is so much corrosion / crud on them.
As stated it would be in the best interest to replace the cylinders and check the rest of the brakes wile you have the drums off.
Hope this helps,
Stay Safe
happy Mopar :)
Arron.
