Yamaha PX-3 belts

[BillWojo]

I have a Yamaha PX-3 that I want to make my daily driver. The tonearm transmission uses 3 pieces of a small square section belt. The Yamaha PN is CB 60 30 40, does anyone know what that crosses over to?
I need to recondition the main flat belt as it slips at the beginning but once it's moved to the record it works fine. All functions work and it's in nice shape.
I know I can remove and measure the stock belts but they will be stretched out some and I'd like to replace with the OEM size.
I have a Denon DL103 (original type) coming for this, anyone use one of these on a PX-3?
Thanks

I've never needed to replace the small belts. I degreased them with a tissue and carburetor cleaner as well as the sheaves and they've been fine. If you get the belt dressing, it would help them.

And a link to the belt dressing:
