ZXR250 rearsets on a 400?

Hi all,
wondering if anyone out there knows of parts that are interchangeable between the ZXR250 and ZXR400 (1992 model) Im interested in getting standard rearsets for my400 so I can compare them to the aftermarket 'race rearsets' I have on the bike. I ask as im finding problems sourcing parts in Adelaide for a 400 and there seems to be plenty of bent 250s around! also be handy to build up my spares just in case....
Thanks

I have no Idea but it is an interesting concept might have to ask RB's or.... dare I say it Sumoto?

sumoto.....they'd charge for the inquirey..then send you down the street and around the corner to the sevice/parts .........per chance a little harsh but got that feeling with the few times i've ventured there
