  good quality and perfect fit
By on 1/30/2014
I am restoring my 1986 mustang gt myself and purchased this seat foam kit. I am very satisfied with the quality and fit of this seat foam kit. I had never done any upholstery work before and found these foam cushions to fit perfectly and really quite easily. I would recommend this seat cushion kit to anybody.

Yes, I would recommend this item to a friend!

  much needed item for a 28 year old car
By on 5/17/2014
I replaced the foam in my driver seat reusing the old upholstery. It wasn't bad swapping out the foam, it seemed easier than the time the guys in the video have with the cobra seats..but that video is a must for anyone looking to take this on. Hog rings are a sinch to put in. Keep an open mind, you may need to push and pull at some of the rods or foam to get a perfect fit. The middle rod on the seat back that doesn't get rings can be tricky if the rods it slips under are spread too far out. In the video, the installers are working with fresh upholstery, so they can cut all the holes they need..you will have to push and pull at the seats to get everything to line up with the old upholstery. All in all, you SHOULD do this for your mustang..I don't sit on the floor anymore!!

Yes, I would recommend this item to a friend!

  Seat foam install
By on 12/30/2013
The foam was of excellent quality. Fit and finish we're perfect. Replacing the foam is time consuming. Video instructions would have be helpful for my exact application, that is reusing the factory upholstery. The video instructions available by Latemodel restoration is must for guidance, "Mustang Upholstery Install: TMI 03-04 Fox Body Cobra Seat Foam & Upholstery". The seat came out great and is very comfortable!
