Donzi:
I have one of these if you are looking for one.
I can't say for sure what all was inside other than the rear antenna cable... my 66 impala (georgia or south carolina ? built)had a rear antenna, which I have removed and welded up the hole in the quarter. Were there other wires for speakers etc in there ? I really don't recall, but I kept that "protector"... why because I never throw anything away ... LOL
Just PM me if you still need or are looking for this part. it was in a box of other small items I was going to sandblast and epoxy prime. Box last seen about 7-10 days ago when I was cleaning out the trunk, so it's not "lost" ... yet
