American Standard Concord Toilet 2004

I'm looking for something to replace the ball float and old water inlet valve in this toilet. In looking for something to replace it, it seems I can't find info on whether they (fluidmaster, hushflo, etc) fit these low profile toilets. Also, it has a side push hande. Therefore not set up as a regular toilet. Can someone help me, or direct me to find any info?

Thanks

I would check this link for parts
