HI
It was quite a while ago so cant remember exactly
What you need is the complete rear seat / seatbelt frame from a US car. It should all come as one unit
I sourced one in Germany , but the US should be your best bet. Place a wanted add.
Fitment was done by my specialist , & with th ecar on the ramps was a straight forward job to access the under side of the gearbox tunnel . The euro mounts for the seat hinges located on the gearbox tunnel had to be removed.
Once all in place, it worked raelly well
Kind regards
James
