Spare tire/trunk rack

[Kahuna]

Model A guys, I need some help. On my way down to see my Mom, I saw a Model A coupe on the highway going in the opposite direction. It had the spare tire on the rear with a trunk rack behind that. It that a normal thing for a Model A? The reason I ask, is that I have a 32 Model B tudor with the spare mounted in the rear and would really like to be able to add a trunk rack to it.
Thoughts?
Thanks
Jim
