Cooker,
Not sure whether they'll bolt right up or not. I do know you can find extensions just about anywhere - most will vibrate at speeds though. As for the CB antenna mount, I'd recommend the Firestik under hood mount. It goes on the last fender bolt, and fits perfect under the hood. Matches the radio antenna on the other side.
