Is there any point to try and make it work on the first 8 sprockets or just buy new 8 speed cassette? I don't wanna throw away the 9 speed cassette as it's almost new and i hate throwing away things that are still in good shape.
And no, i am not willing to get anything newer because budget and parts are hard to find in this country.
you won't be happy with the shifting......
Get the 8sp. cassette.
The slightly narrower chain will work, but may be a bit less quick to shift.... internal bushing width(the part that actually rides on the gear teeth) remains the same, but the outer plates are narrower, and the pins can be shorter too.
