A-body bucket seat floor reinforcement plates

I think these came from Layson's??? It's possible they have two holes so that you use one on the drivers side and the other on the passenger side and they only have to make one product.
That is my assumption, but I didn’t like that even though once carpet is down you never see them…and once I was marking and drilling holes in the AMD plates all I could think about was how much I wish I had bought those 2 hole plates instead lol.
