Factory A-body Dana Wanted

altered A-body said
The Dana 60s they put in the SS cars are B-body units, Your best bet would be contacting Moser. 1500 isn't gonna get you there.

Thanks for the helpful info. So if I buy B-body Dana, it will bolt right on to where the current 8 3/4 is? Do I need to move the spring perches?

Btw, If they use B-body Dana in Super Stock Dart/Cuda, how can you tell the different? Is there casting # on it ?
