In the 2001 Aug. issue (Ithink) of Mopar Muscle Magazine they talk about the Nash bridges cuda. None were Hemi cars they were all clones. If I remember correctly the one don johnson drives is a 440 4spd car. When if I ever get my computer back Ill show you. Or you can search the website for mopar muscle for yourselves
