As per title, I removed the passenger seat no problem at all however the new subframe looks completely wrong and I don't think it's right for the seat either. Autostyle seat off Amazon What I'm left with after removing seat and carpet Sparco seat frame for VW Golf III/Polo 6N/Seat several models/Audi A3 off Amazon. The car is a 98 A3 AGU 1.8t, the seat mounting is 2no. screws at the front in the middle and after removing the rear plastic covers to the runners the seat lifts out. There doesn't seem to be anywhere to fit the new frame. Can anyone point me in the right direction or tell me what the problem is please? Never done this before and thought it'd be easy I also had a look at the existing frame on the seat but god knows how that comes off Thanks in advance.
