steering coupler replacement (how to)

Got the Flaming River piece in and not only does it fit the splines and shaft perfectly but it looks pretty nice too. Looking back I wish I had gone this route from the start, it would of saved me alot of time. Yeah its not cheap but once its in hand, you can see why. I just cut the shaft to size and am drilling my hole next. Happy you suggested this mod Meridian.

How did you get the hole through the shaft exactly? I'm afraid it will drift?
