I am gathering parts for the same, but am using a 42-47 pu rearend center section, so I can have an open drive shaft. I have not located a set of 35-36 axle hsgs yet to complete modified narrowed rearend. It will be atleast another year before I need them, so still plenty of time. Thankfully i have a 47 pu transmission in good shape, so that was the easy part. Rod
