Vinyl was not bad at all. Now that's just a canopy. I'm sure the ones that go down the side in back are more difficult and the ones that go all the way behind rear glass must be a real pain. I just centered it up. Determined how far back I needed for seams on pillars to land where I wanted them. I sprayed both surfaces with 3M super trim. started with strip down center and worked side-to-side It only took 1 can of spray. Just made it, so would need 2 for a full top. Hardest part was the gutters. Like I mentioned that would have been a lot easier on a HOT day.
Are you referring to the Duster e-brake? No problem with it. That was the 2005 Magnum. Was not siezed, pedal went right to the floor...
