Hi there again - wish to fit my GME 3600 UHF C B into mounting space below radio in dash of 2009 D22. Wondering how hard to remove centre dash to gain access to area behind radio / C B cavity to enable coax / power lead / extn spker cables to be run. Already have the coax into cab thru grommett - RHS of engine bay. Also advice on best place to P/U power source. ( Last car came straight off batt - grommett bit tight with spotlight / thermo fan / coax cables + what was thru grommett from factory. Thank you in advance for your advice / help.
