New Mod -- Cupholders-- What do you think?

I was going to fabricate some cupholders to mount on the driver door and one for the passenger side wall. I figured it would cost about $50. Started looking on eBay for plastic drop in cupholders and I found something I thought would not only be less expensive, but would look pretty neat. So I ordered 2 of the ones you see in the photos below. There are no wires in the door panel or on the passenger side wall. If you try this, I strongly recommend you check your configuration before drilling. I had some screw covers I had left over from a different project, so the only cost for this mod was $19.00 for the cupholders. They are the ones you use between the seats of cars.
Thought this might help someone else who might be looking to add some extra cupholders to their rig. Good luck!
