I was going to Ax Vince the same question
I am restoring some pans for my cars and ran into one like the left one
the side where it attaches to the frame is much taller than all the rest of my original pans

The A pans should fit the B engine. The only difference in the pan rails is the rear outboard bolt on each side which shouldn't interfere with the pans. I have never tried it so this may all be wrong but, I will admit that.
