I need to replace the lower passenger door hinge on my 28 roadster. I can't seem to be able to remove the screws no matter what I do. Any ideas would be helpful. So far I have WD 40 them with no results. I really don't want to drill them out.

Blaster and air impact wrench with the tightest fit bit you can get.

Grind your bit to fit the slot with flats along the sides, not tapered. WD-40, the normal stuff is not penetrating fluid. Kroll works good too.

The above are spot on suggestions
Best not to drill. It could leave part of the screw protruding on the back side and not let the hinge come forward to remove. Only solution then is drill bigger!
Is the car painted? If not a little torch heat could help

I bought a large "gunsmithing bit" set on Amazon. At least a dozen different hollow ground bit sizes. I never knew there were so many... I have used this set while working on the A several times. Unfortunately they are not strong enough to use in an impact driver.
 
I have found that peening the tip of the blade to fit snugly into the bottom of the slot grabs at the base of the slot better so the driver has less of a chance of rolling out of the groove when torqued. Good luck
 
try some heat and then touch it with candle wax. A light "rattle" with an impact gun set low might help also. be sure the bit fits tight.

roger that, we had a big to-do about WD-40 previously. The "WD" stands for water displacement. As I recall today, it was a product that came out of the space program in the 1960s for some purpose therein. Back then it was generally assumed by the public to be some miracle deruster/lubricant, which it was not.
 
I had to resort to welding a bolt to the screw head to get enough torque to remove them. Impact driver worked on a couple.
 
Sometimes a square shanked screwdriver is nice cause you can lean in on it, while a buddy puts a wrench on it.
 
This has worked for me with very crusty door hinge screws . I assume you are not concerned about paint at this time . Heat the screw head very hot but not yet cherry dowse it with cold wter . Use a good quality impact driver and a snug fitting bit . A few hefty bops should free it .
