To get a match you need to know the dimensions as well as the shape. That particular profile comes in several sizes. The width and thickness of the base has to be correct or it won't fit into the slot in the door. The height of the bulb has to be right, too short and it won't compress enough to keep out the water. Too high and the door won't close.
As to fitting it into the channel, it is flexible. You flex the edges of the base towards each other to get it into the slot then let go. One useful thing you can do to lubricate the seal for easier installation is apply some glycerine so it slides in with a lot less resistance. Glycerine is a very slippery liquid. But since you need to keep a grip on it so you can push it around while you install it brush the glycerine inside the track and not onto seal. Or at least apply it only on the lower flange of the seal and not on the bulb.
Glycerine will not hurt the seal or cause it to deteriorate. Some car makers recommend applying it to the door seals to keep them flexible and reduce the rubbing friction on them.
