I'm trying to order new T-Top seals for my 88 IROC. The dealership says that they have two types: With "interlocking slider bracket" and without. The seals with the 'interlocking slider bracket' is no longer available---The one without the interlocking slider bracket is. NO ONE that I've contacted knows what that means. A couple of dealerships have mentioned about a first design and a second design but they don't even know what that means.

Any help would be deeply appreciated. I can also be emailed directly at Ryans2kidz@aol.com. Thanks!
