what is up with cab corners

[jhrusk]

I just received a set of cab corner patch panels,I bought them from a vendor that is known for selling the best stuff available.I am in no way bashing the vendor I am very pleased with them.On my other truck I bought a set at a car show and they were the same way.They are not even close were it attaches to the rocker panel,they have a key part sticker on them.They were only 16 bucks but I would certainly pay more for ones that fit better.Does anyone know of any better pieces ???60-66 c-10.Thanks.
