88 Notchback-need A Rear Seat Delete (template Or Dimensions)

[Fester7799]

I am in the middle of a 88 Coupe build (331 w/ Kenne Bell SC), and I just put a MM 6 point cage in my 88 Notchback. I am looking to see if anyone has the dimensions, or one of the old templates for a rear seat delete kits that used to be sold. I know there are about 20 places to get them, I was just seeing if anyone had the template. I am working around the cage, so buying a new one and cutting it up is not the first thing i wanted to try.
