You will need side-mount aftermarket rails; bride rails/buddyclub/PLM/vision etc
Yonas @ JDMYard sold me a PLM rails for 150 new. You can find second hand on these forums as well - but that's your choice.
What if he has a bottom mount seat? Threadstarter do you have a side mount fixed back seat, or a bottom mount seats (Recaro SR3/4 style)? If you have the latter then EK9 seat rails will work, otherwise you need something aftermarket.
