What spark plug wire parts fit ARDUN heads?

Early Chrysler Hemi parts, because the ARDUN has similarities to the Hemi, including real deep spark plug wells. Steve names the 331, 392 and 354 Hemi as he recalls them. The parts do not fit perfectly: the insulators were too big in diameter to go down the ARDUN tube, so he trimmed them about 80 thousandths in his mini lathe and they fit.
