Have you looked into changing that coax connector that protrudes from the side of your center console with a 90 degree connection? (just like the one you have mounted to the radio itself) It looks like it would take just one poorly executed "sit" to break that current connection. It would also ease any "pulling" action felt by the cable itself.Another project that I worked on while I waited on parts was a custom CB mount. I Googled hidden CB mount and saw a location from a guy on a Yota forum that I wanted to emulate. I don't use the radio too often, so I thought the area would work well and I'm very pleased with the results.
just a thought. Nice install though, looks clean.
