I have a dana 60 rear that I am not sure what it fits I have tried to identify by the numbers off the tube it appears to be a 9 3/4 3:54 gear out of a 1966 (can't figure out what body). The numbers on the tube are 118 6B1 2829 7 and an A9 23 1. The ring gear # 12/4/65 Dana 32503 A3D25 46-13. and the Posi 25 124 X 1/7/66. The casting numbers on the center section are 2018188 and 1968618 034165 60. Any help would be greatly appreciated. Thanks

I believe that the only DANA 60 available in 1966 was for B Body cars. There were no A Body DANA except for the 1968 Hemi Dart/Barracuda. and the E Bodies were still 4 years away. The only models that I can think of are the Coronet/Charger and the Belvedere/GTX. I would also safely assume that the DANA was only offered in HEMI cars.

Maybe this will help
