hello............

 

are there any holes in the cab roof? Maybe someone fitted an extra antenna on the roof at some point?

Seems a bit strange to me!

I wasn't aware they had CD available in '94. The last Bronco I saw with that spliter had the factory hand held CB option. Never really paid any attention to where it went becuase the hand unit and the radio had already been changed out.
