I searched, but unless I'm going blind, I can't find specific answers to my question. I'm installing an OEM Euro GT3 Seats in my car.

Where can I find the "by the book" torque values for the following bolts?:

-Seat to Seat Brackets(4 bolts).

-Seat Brackets to the car chassis(4 mounting bolts/E12 socket).

Thanks very much!

Oh and the stock seat belt to chassis bolts please.
