Garvino, I went the Mr. Mikes Fiero seat route as well, but I ended up having to bolt them to the floor with no tracks. Even had to cut the carpet out around to bolt holes to get just a smidgen more headroom. I'm 6' tall with a long torso and as it is, I barely fit in the car. Depending on your height, this could be a problem. You could substitute thinner foam on the seat bottoms for more headroom.
I think I paid $550 for the kit and another $50 for the seats. Mine have the speakers in the headrests and this helped the stereo immensely. I put new speakers in the headrests before recovering them, so that is an additional expense.
I'm not sure where you are in Wyoming, but I'm in Greeley CO so I might be just down the road from you. You're welcome to come over for a test fit before you buy. Might save you some dissapointment and expense!
