im trying to replace some seals since i have oil leaking into where my brake drums are. i figured i would do both sides. I tried a impact gun with a 1/2 inch drive drag link adapter but the screw head just gets deformed.

Welcome to HEF, Mike !
Do you have the service manual ??

Heat cycling with a cutting torch will help immensely Air hammer would be the next trick https://www.amazon.com/Pneumatic-At...8c-bd9f-1002604ab448&pd_rd_i=B09CDHRK85&psc=1 The vibrations go along ways to breaking the bond
You could recut the slot with a die grinder cutting wheel
And a not to sharp pointed chisel in an air hammer can push it around counter clockwise you would be surprised what that will unscrew
Even some sharp hits with a 3 pound hammer on an extension and your drag link socket is worth a try but not as good as an air hammer

If you have a welder, Welding a nut on the screw will do two things... a larger grip and the heat of welding will help break it loose.

Hand impact and hammer..
If it doesn’t budge, heat the body, not the screw..

Have done hundreds, sorry to disagree with thepumpguy, I know he will forgive me, but heat the screw head red hot, let it cool and it will screw out easily

I do have a service manual. Took forever to find it online.

I was too nervous to get the screw red hot if oil might be on the other side so i drilled the screw head off. I wonder how important it is to put those screws back in anyway? Maybe i should leave them out if it all gets held by the bolts on the outside anyway?
