23 splines?
thats weird, i know the mopar cars that came with the Dana 60 where just the 440's and Hemi's 4 speed but never imagine they did come with 23 spline axles really weird.
The Richmond 5 speed trany, this is for a street car that will see track at least once a every two month but it will be strictlly a street Big block 440 dart with about 500 whp and 600 of torque?
