My '55 is a 4-speed and she won't drive a manual. My '72 is an automatic, but its too big... She won't even climb into my big bolts.
I'm building a '54 3100 just for her. It will be automatic with power steering and brakes, lowered and I might even shorten the bed to make it feel smaller.
I have a power seat that goes up and down in addtion to fore and aft. It will be installed so max up and max forward just fit her (she isn't very big), so it can be moved where I can drive it, since I'm sure I'll be the primary driver once its done.
