MAZDA..
I suppose you know you need to change the "toung" for AE86 as well, right? You can't just take the AE86 cover off and try to slip it into the chassis..... It's the part in the front of the chassis where it holds by 2 screws..........
If you still have no idea, I suggest you bring the car and the cover, get on a cross tunnel bus and go to a place call KWS or any of the two track and they'll help you there....
