I have my dash apart and I'm trying to mount my Cobra 18 WX ST II underneath my aftermarket single din receiver. For the people who have this installed, how did you mount this to the stock radio mount? Did you drill new holes into the stock mount? Did you use the black radio mount for that came with the radio for anything? The stock radio mount holes don't line up with the single big hole (on each side) of the CB. I can make it line up but it forces the radio to sit back 1-2" from the receiver. Any input is greatly appreciated.
