Top/Frame Rubber Seal Installation, Help Options

[jfort]

I bought a "door-window frame to top-door" seal from 914Rubber. It's all one piece. The frame to the forward edge of the door/side windows, each side, goes in easily. It is the horizontal, leading edge of the top to frame seal that is giving me fits. There is a "C" shape that fits over the knife edge of the frame.

I read somewhere that you just have to push very hard on the back of the "C", that is, the whole seal, to get it to stay on the knife edge. I can't push hard enough apparently. I have Vasolene all over, too. (Had to get the rubber part of the seal back to surrounding the metal "C" thing that goes inside the rubber.) Is the Vasolene preventing the seal from sticking or snapping into place? There is no barb or edge on the frame/knife edge to grip the seal. What holds it in place?

Need some advice from someone who's done this. Thanks in advance.

Thanks for the replies, guys. Don't know what I'd do without this community.

I will pick up some Dawn to try to clean up the Vasoline and to lubricate the install. I have every solvent known to man for that, too. Maybe I'll try some glycerine, too. I have a rubber mallet, wood block, screwdriver, etc. Starting the top at the center makes sense. Getting the metal back into the rubber after failed attempts is a bit**. I'll post how it goes.

I'd rather have it too tight than the other way. Looks to be a quality product, but I can't rest until it's on.
