I totally agree.....
I had to fabricate a lot of stuff to convert from the factory am/fm/CB radio to the 40,000 color Sony radio. The original factory radio didn't have a manual antenna switch. The antenna mast automatically raised up when you turn the radio on and retracted automatically when you turned the radio off. So.... I had to find a donor power antenna switch and fabricate a wiring harness for the factory power antenna that you have. I had to cut a hole in the dash to mount the antenna switch. I also had to take the FN hood and wheel, inner fender, and all the other crap to install the power antenna (that I got from Mr. C) and I had to fabricate that part of the wiring harness too. Had to replace the blower motor too. And rebuild a lot of the Manual A/C box and replace the controller, resistor, fan switch, all the dash lights, etc. New speakers front and rear and wire those and run them under the carpet. It was quite the task.
