DRIVE SHAFT TRIVIA

Recent work on our 1968 Coronet included the build and installation of a new drive shaft.  This activity proved to be a practical exercise from which the information gained is directly transferable to the Charger restoration project.

Pictured above is the forward sliding yoke from a drive shaft that connects to a MOPAR 727B transmission. It has 29 splines to handle the torque developed by big block MOPAR engines.

Our Charger came from the factory with a 318 cid engine, 727A auto transmission and an 8 3/4 inch rear differential with 2.76 gears.  We will be upgrading it by installing the 440 cid engine and the 727B auto transmission we removed from a 1976 Winnabego. This will be done after the engine and transmission have been over hauled and after changing out the transmission tailstock for one used in passenger cars. We will also up grade the rear end with the differential we recently purchased (489 case with sure grip and 3.23 gears).

Because of these changes the Charger will also require a different drive shaft. It must be the proper length and capable of handling the increased horsepower and torque.

Using the sliding front yoke shown above we will either purchase or have made a driveshaft that is 3 inches in diameter and 52.07 inches in length from c/l of the front yoke bearing bores to the c/l of the rear bearing bores.
