14" 5 on 4 1/2 SPARE RIM
I use a space saver rim and tire from a Jeep Cherokee in my 68 cuda. It's skinny and fits in the well, saves a little weight, and the well cover sits flush. I consider it for emergencies only so the small tire doesn't bother me. It fits my 73-76 BBP disc brakes in the front. Think I paid $15 at a junkyard for a never used one.
