I got my hands on a brand new set of 2010 ZX-10R calipers and M/C, anyone with ZX-6R forks done this upgrade?

My biggest questions are do I worry about using the M/C or keep the OE Z1000 one and what spacers will I need for the calipers to fit my 03-04 model ZX-6R forks. 10mm or 5mm?

I use small 2mm spacers with zx10 08 calipers.
BUT my front discs are big,320mm and my fork has longer caliper brackets than yours because is coming from zx6 07 with 300mm discs,not 280mm as your fork 03-04 model does.
SO,you have to machine down the calipers,maybe 8mm(impossible) if i am right.
