I believe either could work. One was designed for models that plug directly into the board(4) and the other (3) would mount on the board and wired to the terminals. The 66 barracuda used neither but they both can be "wired" in the same way as the 7805/ heat sink/ resister modification that can be found in a few posts. If ya are not feeling like soldering up the small cheap parts You can use the RTE products.
