If there is much interest in the straight sheet metal section at the bottom 2 or 3 inches at the lower rear of the cab, I'd consider making them. The only real problem would be that there's a difference between the offset lip of OEM and different aftermarket cab corners. It might be possible to match them up with OEM and then the brand carried by Chris and make two versions. I'd guess I'd be able to do 4' sections to ship them at a reasonable price. Let me know on here if you would buy them and what a reasonable price would be to you and I might send Chris a message about doing them and selling them through his store.
