Don at MXprographx used my '84 and made a template. Just make sure you tell him to use the darker yellow if you put any yellow in there so it matches the old RM color.
Don's stuff is the best we have ever used. Years ago after being on for 1 year we peeled the backgrounds off the kids 50, put it on the new one &
they stuck like new plus 7 years later are still sticking to something in our garage as he uses some very good material & is great to deal with.
Glad you reminded me of him as we need to get a few sets made soon.
