As most of the older vehicle projects I've gotten into, the weatherstripping, almost all around the vehicle, is worn, cracking, etc. This is something I have no experience with. Any input as to replacing any of it? For starters, let's say window stripping, down where the door meets the windows? Or, for 4runners, the sliding windows on the sides? Rear window? And not only installing it, but purchasing it? I've noticed JCWhitney has many, MANY different styles, shapes, etc that you can buy to match the OEM stuff.
