Calling all 60-2 Valiant and Lancer owners, info needed

I believe they were the same, both shape and material, from'60-'62 but I can't say for 100.0 percent due to the fact that where I'm at I'm usually vacuuming them up rather than removing them semi-whole. There may have been slight color differences since '60-'61 blue and green interiors are a shade or two different than '62's. I know the one I purchased came from a vendor in Australia. I do agree with other posters that cutting cardboard and covering with fabric/vinyl works well and has held up over time. I do remember the upholstery guy complaining about the vertical rise in the package shelf because it tapers down as it goes away from the car centerline. He measured it at the middle, the highest point, and made the first one at that constant height rather than tapering it toward the ends and ended up remaking it. Also on my car he used 1/4" backing under the vinyl and it would be nicer for fit and finish if it were thinner like the original cardboard was. So any future ones I have done I'll likely specify thinner backing, maybe 1/8, under the vinyl.
