Power Antenna Question

You can find Mopar chrome bezels on eBay. Barracuda is unique, and 67 is different than 68-69, but you don't care about that (and some B-body ones are almost identical styling). What you need are a nut that threads onto the antenna base that you have (this should be part of the power antenna kit), and the double-semicircle widget that goes under the fender. The sticky issues are: Does the power antenna base fit through the hole in the bezel? Is the nut big enough in diameter not to fall through the hole in the bezel? If not, you might be able to find a chrome washer. Is the overall length of the antenna base correct so you can tighten down the assembly with the bezel you chose (as opposed to the generic plastic bezel)? You might be able to space this out under the fender with washers, too.
