Hi Chuck: I did get hold of Simmons and they do rib matting if the rib is flat. They, at this time, cannot do concave ribs---they are working on it and maybe will be able to do concave in the next 60-90 days. Someone mentioned they did a lazer cutting for the ribs, but that is not true, they only machine cut the flat ribs at this time and the cost is about $200.00. Thanks for all the suggestions and I will let you know what happens in the next few months.

Ralph
