'03 Z1000 steering damper help

Hi!

I just joined team Z1000 as I bought a '03 model. Now I'm wondering that I probably should buy a steering damper for it. I could buy a new kit (€€€€), but I'd like to save some and buy used. What specs would fit the bike and what specs should I look for?

I noticed an ÖhlinsZX-10R 2019 damper for sale in my area. Would it be a possible fit? Local dealer also hasnew Bitubo's in stock.
