Thank you Teach & Giddyup for excellent suggestions. Teach's alternative suggestion intrigues me quite a lot. "Ultimates" was referred to in the post, if you have a chance, help me out with what that refers to.

I took another look at Corbin's offerings, great looking total solution to replacing the whole seat and backrests, but that price will buy a lot of double cheeseburgers as a friend of mine says.

Anyhow, Thanks!
