Rear arm rest bases

[John]

I am in need of replacing the rear arm rest bases on my 71. Many online restoration companies sell these reproductions. I ordered a set from Ground Up and when I received it noticed several things. They don't have the detail for one. The side piece that runs up the side of the rear seat is plastic and doesn't have a way to fasten it to the base. I am sending them back. Has anyone purchased an aftermarket set and found them to be accurate?
