Chuck, Aren't you always there with parts? 

 

Here's to hoping I can make it too.

Thanks! I'll let you know how it goes.

I got my Z back on the road two weeks ago. I used the ball bearings from McMaster Carr (see Post #10) and they work perfectly (no sound at all from the bearing now). I actually added two additional bearings (32 in total) and the steering feels great!

 

Of course over the winter I also replaced the strut inserts (Tokico Blues), ball joints, tie rod ends, strut bearings, steeing rack bushings, inner control arm bushings, and installed the Motorsports Auto Tension/Compression rod kit (http://www.thezstore.com/page/TZS/PROD/classic20j/23-4190, highly recommended!) and new front tires (Dunlop Direzza ZII Star Spec) so I'm not sure how much the new bearings contributed to the improved steering feel. But the steering feels awesome!

FYI the ball bearings in 1/2 shafts are 7/16"  http://www.classiczcars.com/topic/39774-halfshaft-internal-ball-bearing-hardness/
