the flywheel bolts you should get oem, but as for the other stuff you can get it basically anywhere. I bought all those bolts from an auto parts store. They had to order it from a bolt supplier because it was heat treated metric, but I still got them that day. I think it was about $20 for the lot. If you just want to buy one or 2 to test the size, Home Depot has a large selection of metric bolts.
Im going from memory here, I think the pressure plate bolts are M8. Bellhousing bolts are M12, and a couple M10s. All are coarse threads. All are Grade 9.9, but its easier to get 10.9 (Imperial grade 8 equiv.)
Bellhousing bolts off the Ka are the same size (diameter and thread pitch) but the lengths are all off. The pressure plate bolts are the same size, but there are 9 bolts on the PP (SR) and only 6 on the KA.
