Speed Queen Solenoid Drive Belts?

[panthera]

I'm happy to say that (largely owning to the help we got here, and parts from Eugene) the Speed Queen timer is still chugging along perfectly. May be the only one with old 'dogs' on earth. Now that I have a brass replacement for them, they'll never fail.
But, what appears to be the original drive belts are failing. I'm afraid to touch the pump, noisy as it may be, so I'm glad to say it's not dragging on them.

Here's what's on the belts:
Speed queen 20186 DE
Speed queen 20185 DF
Speed Queen 20185 dunkee atwood 4l280 ID

I'm guessing somebody here knows where to get new? I'd appreciate any input!
Thanks!
(As somebody will not have followed the summer drama, the model number won't help, it was a special model and there are zero references to it on any parts site. These will be the same belts as all solenoid units from '69 and that era used.)

Here’s some new old stock that’s probably been on the shelf for at least 30 years but I’d buy it if in your situation.

And the 20186.

As Melvin pointed out you can find plenty of Speed Queen or RSPC belts on eBay with the original belt part numbers that you found on the belts.

I’ve had luck with generic ones, as well.

20186 - 48-360, or in a pinch a 4L360
20185 - 48-280, or 4L280

What year did Speed Queen switch over from aluminum agitators to plastic?
