I have a ford ranger and since space is limited I want to hang it from the headliner. Has anyone ever done it before? I did notice where the visors are screwed in at are very tight, but there is nothing in the center. What should I do to hang a radio from the headliner/roof? The radio,s that Iam considering in using is a galaxy 929 or a cobra 29 special edition chrome verision. any info would be helpful thanks.
