We had one in a Ken Cox funny car ch***is , it had Ramchargers cast into the center section and as recall used 33 spline axles there was also a heavy bolt flange cast into the pinion area for a coupler shield .
I bought a neglected, old Pro Stock '70 Camaro from somebody's back yard that had a complete magnesium Ramchargers Dana 60 underneath it. Pretty rare piece and very cool.
