I have never seen a Ford R&P set without a hole in the splined pinion shaft. Just wondering if that could be a cut down pinion, possibly from a long shaft Merc., and they did not put the hole through the resplined pinion shaft? In any case, it would be best to have the hole, but it's not going to be easy to drill if the pinion spline is hardened. JMO
