Description Installation


Designed to fit the 1994-2004 model year Ford Mustang Cobra. This high quality convertible top will keep your Mustang looking its absolute finest. Includes a new heated glass window.


New DOT rated glass window is bonded into the rear window section. From the exterior, the edge around the window has a clean, finished appearance with no piping needed to hide stitching, gluing or imperfections that may arise from other bonding methods. The fabric has been carefully notched by a computer controlled cutter around the radius to ensure proper adhesion around the entire perimeter to eliminate potential leaking. The technology is unique and protected by worldwide patents and we guarantee the bond to the original purchaser for the life of the vehicle.


Haartz Twillfast RPC is considered an Acoustic topping and reduces noise. Acrylic face and polyester backing. Backing is black and has a Dobby (crosshatch) pattern. Haartz cloth topping materials are constructed using a three-ply method that has an acrylic or polyester/acrylic exterior (facing) and a cloth lining (backing). These materials are combined using an elastometric or rubber film that is sandwiched between them. This provides waterproofing and gives the material its stretch. Increasing the thickness of the rubber film will reduce the amount of noise in the vehicle interior. These thicker toppings are referred to as Acoustic and are becoming standard on most new cars.

Made with Haartz Material

In model years 2000-2004 Ford added a rubber weather seal sewn into the top that provides additional protection to the interior from the weather and some reduction to exterior road noise. This weather seal is sewn into all of our Mustang tops.

  • Includes both rear window and main top section
  • Haartz premium Twillfast RPC canvas
  • Tempered glass same size & contour as original
  • Factory style extrusions for an easier, more accurate installation
  • Includes rubber weather seal as original in later model Mustangs
  • Top is 100% GUARANTEED to fit or your money back

No sewing is required. It comes completely assembled and ready to install.

5 of 5 Looks great and fits great July 19, 2023
Reviewer: Isaias Rodriguez from Los Angeles, CA United States  
Top came as advertised and arrived fast in 2 days. Quality is great and fits my mustang GT super good. I like the top much more than the vinyl top the car came with. Everything about it is great. Window is not an OEM Ford window but it’s still a good window in case anyone was wondering . I like it alot and I’m very happy I ordered it.

5 of 5 Very happy so far August 24, 2020
Reviewer: Kim from Mississauga, ON Canada  
When it came time to replace the top on my 1999 Mustang GT researched the most popular brands and materials. I found it difficult but in the end I decided to order the Sierra Brand top from Auto Tops Direct. The website states that most orders are shipped within 24 hours but the sales rep on the phone told me the Mustang tops weren’t in stock and it would have to be put into production which would be approximately four weeks. I also understood that there could be delays at the border so it could be quite a while before I received the top. I ordered the top on a Monday and to my surprise it arrived two days later on Wednesday. How they manage to ship from California to Ontario in such a short time is beyond me. I haven’t installed the top yet so can’t can’t comment on that but everything that came looks fantastic. I ordered the top, tension cables and headliner. The pads weren’t available so I was thinking I would either reuse the original pads or order them from an alternate source.
