Existing R-Panel with Odd Dimensions

Need some help....I have a customer with an existing R-panel roof. This roof appears to be old and out of date. I get it that a lot of these roofs are produced on rollformers owned by the PEMB manufacturers and this one may be "extinct. Bur here are the specs....1.5" high ribs, 10" center to center of high ribs, and 33" wide coverage...all of this in lieu of the typical 1.25" ribs, 12" o.c., and 36" wide coverage. Any help would be greatly appreciated. Thanks
