I didn't have any luck last night at Malmberg. The guy on the counter was playing the "I'm only the night guy" game. With that attitude, he'll be lucky to stay as a counter guy, more likely he'll progress to floor sweeper (hopefully one way, out the door). I'll try again today when the day staff are in, maybe at the driveline branch instead of general service.

I went back to Malmberg this morning. The day shift was much more willing to help. Once he'd been through his catalogs he went out back to do something. I'm not sure if it was to rest his brain, but more likely to consult others and check if they had any ideas about what he'd missed. The consensus was that what we're looking for falls between the light duty car/pickup/trailer market and the heavy truck market and that the truck driveline aftermarket isn't making these washers easy to find anymore. They suggested trying a GM dealer in case the part was still cataloged. I had tried an online search this morning, but may try a dealer to see if they are willing or able to find something the online missed. Do you read the C60 parts list as giving a number of 1810181 (replaced by 1811151)? Is there by any chance a part number stamped or etched in the old washer that could be cross referenced? (Sometimes on the edge to keep the rubbing faces smooth.)

I have asked some of the AMEs here in the hangar if they have ideas where to find such specialized washers and am waiting for their answer.

Next point of trial will be General Bearing Supply, there are some staff there who are willing to take on a challenge and don't like to be beaten. They were able to find a few NOS 928 bearings in the UK, but a few turned up locally much cheaper. Perhaps they'll be interested in this challenge too.

Another way around it might be to find some of the bearing adjustment lock washers that fit a keyed shaft and have multiple external tabs, one is bent inward against the adjusting nut and another outward against the lock nut. This only applies if there is enough space, I haven't seen or tried it. This style lock washer was used on the M135.
