Hi Joe,
Thanks for responding. You may have better luck if your working on your 1970. They have a slightly different style for '70 vs. '71-'74. Mine is a 1971 Barracuda. The ones they sent me appear to have been assembled wrong making the gearing off. Since yours is a different model year you may be more fortunate.
I'm also need a plan "B", can some one direct me to a good, used, '71 Barracuda, Driver Side Window Regulator???
