Fuji Regis crank puzzle?
I am restoring a 1985 Fuji Regis road bike and have it completely disassembled. When starting to re - install the bearings for the crankset I suddenly realized the drive side of the crank has an extra race which I cannot figure the correct way to install the bearings. In all the other old Fuji bikes I have restored this is the first time I have come across this problem. Normally I coat the race with grease which holds the bearings in place while I reassemble it. This inner race prevents me from using that method. Has anyone any suggestions

That looks like a sealing ring.
These wedge-profile rubber rings were used just outboard of the bearing retainer on both sides of the bike. It takes up space that would normally be occupied by grease and/or an air gap, and was presumed to help keep dirt from entering.
Was never a thing on higher-end equipment, only on entry-level bikes that perhaps had bigger clearance gaps between cups and spindles that had fewer machining steps in their manufacture.
For the life of me I can't recall which way that the seal's shape is oriented, only that it is outboard of the retainers inside each cup.

That makes sense but why not on both sides? Still don't know how to get the bearing balls to stay in position when I assemble it. Too hot to think straight today. Maybe it will come to me when its cooler!

If it's a sealing ring, it should just slide off w/o any significant resistance. The opposite side should have one too, maybe it's still lining the spindle hole in the cup? Or it may have been lost in a previous servicing; old bike and all.

Of Course! Now I feel like an idiot. That's exactly what it was. Don't know how it did not come off when I was trying to work around it.
I just went out to my workbench and it slipped off so easily I could not beliew it. Thanks, guys for the information.
(I'm going to blame it on the heat!)

Don't bang yourself up over this one... 
You identified the problem, described it in a concise way, and reacted with understanding when your well-meaning peers gave you good advice.
It's nice to see when it works, and this is why I keep coming back here.
