ok here is the break down:

the 3g FRONT integra seats from the 94-01 2door will fit ur car but u have to swap ur 6g civic seat rails over to make it fit in like oem utiliziing all 4 mountin holes, otherwise boltin in the stock integra seat, u will net only 3 of the 4 mountin holes and thats retarded and unsafe.

the 3g REAR integra seats from the 94-01 2door is a 50/50 partition back and the seat cushion has a middle tray. ur 6g civic coupe back is a 60/40 partition and the seat cushion is all cushion. the seat bottom of the teg seat will fit but the back will not have the hinge to lock the seat in place as it is made for a 50/50 split with locks on both side.

the only way to get the back to look nice is to get the 3g REAR integra 94-01 4door back because it is a 100% 1 piece back so it will bolt into ur 6g civic coupe no prob.

the door panels will not fit unless modifications are made to the panel and ur door because the door handle and other misc stuff is in different locations and the dash and the door panel will not line up and modification to the door panel again has to be made, too much work for not much of a difference.

and the 3g integra seats whether it is leather or cloth, my guide works on both as the fabric is the only diff and doesnt interfear with the mechanical aspect. have fun.
