I've had that on eBay for over a year now and forgot that it was set at $16. I'll update my above post. Anyways, custom ones will be $18shipped due to setup. I just did one for Justplainjane, so here's an example:
I have a Cascade Innovations 30" Red Rear Brake line for sale for $30shipped and it has all of the hardware that comes with the kit. This line is used for a 12" over round housing or a 6" over stock carrier.
I make and sell custom CNC'd aluminum Rear block-off plates. They are $18 shipped and include stainless bolts. If you would like a different design engraved into them, please feel free to contact me and I'll see what I can do. I also offer a plain polished version as well.
