The following text is from Restauration guide (Paul Herd):
A 60-inch manual-control antenna was used all eight years (67-74). However, some cars in 1969 to 1971 did use a 76 1/2"-inch-long manual antenna. On all models except those with the fiberglass hood, the antenna was mounted on the right front fender. Those models with the fiberglass hood had the antenna mounted on the rear quarter panel. The 1967-1969 models used the same antenna that was used on all A-bodies and 1968-1969 B-bodies.
With the 1970-1974 models, except those with the fiberglass hood, the antenna was designed specifically for the Challenger or Barracuda line only and will not interchange with other car lines. As previously mentioned, those models with a fiberglass hood had the antenna mounted on the rear quarter panel. This antenna can be found on Dusters, Darts, and 1972-1973 full-sized Dodges, Plymouths, and Chryslers with a manual antenna. A power antenna was never offered for the Barracuda or Challenger as original equipment.
Hope it helps and is correct.
