164 to 240 Diff Center exchange
I would like to swap the diff center on my 1974 164 (3.54:1) for a 3.91:1 from a 1976 245. Will the 3.91 bolt straight into the 164 diff housing? Does the pinion have to be changed, and are the splines the same on the drive shafts? I would appreciate response from anyone who knows or who has done the swap before.
