The thought continues to haunt me "what if I get a flat on a rear tire?"

If my car had the original size tires 8.20-15 (I believe), would this size clear the fender without jacking the car up so far?

When I installed the current L78 15 tires I had a floor jack under the frame in front of the wheel with the skirt removed. I had run out of jack when I got the car far enough in the air to remove the tire past the fender opening.

My '48 has L78s on it now, which are way to big. The original tire size for the 22nd series is a 7.60-15, and that translates to a 225 75R15 radial.

My car still had the original size 7.60 15 spare, and it is 3/4" shorter (radius). That's 1-1/2" less than the L78. No wonder there was interference when changing a flat.
