Secure the loops with 11" zips, you will need about 20 11" zips to get a great fit that stays put, plenty of room to zip them up associate. The "leather" is a little better than expected but I want it to be leather on all sides, the sides are thin fabric and the back and seat are not connected as in the photo, they are 2 different parts . Like all seat covers, they sit a bit sloppy in the corners. My headrests are in stock. 2001 frontier t/c.
