Here is a link to the Precision 67 A-Body pieces. If you look at WLS DB 3861-67, they are listing the application for the 67 Barracuda notchback application. They do not indicate that the corners are included and the picture shows only three pieces so you would have to cut one of the pieces to make up the four pieces. I will have to contact our rep in regards to the particulars. I have sold a number of the convertible and fastback kits, but have had people purchase the windshield kit and use it for the rear window. To be honest, I had never seen it listed for the notchback application until just now when I pulled it up.
Do not purchase the kit with the mylar trim that is flexible and is rolled up as it is the trim as used on the 63 to 66 A-Bodies or the truck applications. The 67 mylar pieces are rigid and has a wider profile making them a one year only piece.
Do not go by the pricing as listed on the site. Most of us vendors for the Precision product line sells it for a lower price. The only issue currently is getting some of the product, but that is no different than anything at the current time.
