rsx back seat

[civictypeR99]

Hi sorry for my language im french i will do my best, so i saw some rsx back seat in leather for sale at a very good price, i wonder if they could fit in my honda hatchback 1999, it is not an ek9 sadly.
Do i need something extra with the seats? Or is it bolt-on?
Thanks for help

Hi and Welcome. Check out this link How To: Install JDM ITR Rear Seats (Backrests) into 96-00 Civic Hatchbacks with PICS!!* - Honda-Tech

Edit: Just saw that you wanted DC5 rear seats. That thread might help though.
