Change tubular drive line from 10 to 6 spline

[larry/Texas]

I have a "33 tudor and am looking at buying a new 3.54 ring and pinion to replace the current 4.11 ratio. The new pinon has a 6 spline pinon and my drive line is tubular (32-34) with a 10 spline female. Can someone advise what to do to make the new 6 spline pinon work with my existing drive line?

Has anyone made this change and if so, how did it work out? These new ning and pinon are available form Drake, Mac's and others but there is no further information in their catalogs.

Thanks in advance for your answers.
