I just installed vaders im my 4 door pretty straight foward you do have to cut a small square where the seat belts go but if you have a a small dremmel tool it is very easy as the vaders have the mark where it needs to be cut out the only thing you need to woory about is the passanger seat having the seatbelt and airbag sensor plugs so before you purchase remove your seat and check what plugs you have and compare to what you are buying I cannot find the vaders that I need and my airbag light is on, you say why not use the ones from the old seats well the airbag sensor is inside the seat and you need to use the cushions from the seats does not fit and the seatbelt sensor has different mounting points, from what I understand 95-96 had no seatbelt sensor on the passanger seat 97 has a black 3 prong sensor for the belt and a white 3 prong for the occupior 98 has a black 4 prong for the belt and a black 4 prong for the occupior not sure about 99 but I think the same as 98
