Oddjob:
Shouldn't be an issue, I think the shells don't cover the entire surface anyway. If they do just dress it down a little, won't affect the clearance unless you do the entire surface.
I have 6 yellows if you need them, £15 a shell inc P&P.
I just checked and have 12 yellow mains as it happens.
Still in sealed original bags.

Yes that's right - gotta think of these as pairs!
Also, looking closely at the cases and noticed this nick on the top case at the clutch end journal (see photo). How big of an issue is this?
And why doesn't the middle slot on the top case (3rd from rotor end) have a lubrication hole or slot? It seems like the only one on the top and bottom cases?

Weird optical illusion when you click on the photo to enlarge it slightly - if its the edge part you are talking about as long as the bearing sits in the shell I do not see that as an issue.
I noticed the lack of an oil slot in the centre crank journal - it does seem odd.

Ok noticed something very concerning when offering the crank to check clearances with plastigauge using the old shells.
Please correct me if I'm wrong as I'm counting journal positions from the rotor side of the crank.
I noticed theres no clearance between the crankshaft and the 2nd crank journal positions and this has obvious signs of wear, especially on one side.
All the other positions look to be ok with clearnace on both top and bottom cases?

This is what I have just so I'm not crazy 🤣
Took another photo with the shell in but you should see the nick. I don't think it's an issue as the shell is stationary but I'm being careful as I can.
Bryanj:
One journal has less clearance to reduce end float, cars have specific thrust washers but then they also have clutch end load
