Has anybody used seat covers from Seat Covers Unlimited?
http://www.seatcoversunlimited.com/They say that they are specifically cut for each application and they do have Chevy Monza listed. I'm thinking about ordering a set of Leatherette covers. Currently $235 a set for the front seats.
Full Custom is our most popular option for several reasons. It is a guaranteed fit as we make the covers specifically for your year make and model. It has the full fabric of your choice all the way around the back of the seats and around the bottom edges of the seat. Full Custom not only looks nicer, but will hug your seat tighter, therefore lasting longer. With the full fabric backing, adding map pockets is available. It is a cover for those who take pride in their vehicle.
