That chain is well knackered if my sums are correct, 20 links x 0.625" = 12.5" = 317.5mm. The OP has measured 321mm = 0.0065" wear per pin 6.5 thou in real money. That = fecked.

Dunno why we have metric dims on chains that are made in imperial sizes.

Go buy a full chain & sprocket kit & be done.

The rule of thumb I was taught was if you could pull the chain back and see more than 1/2 tooth it was time to replace the chain. Not doing the sprockets is probably a false economy.
