You may have better luck if you attach a picture of just one or two seals at a time since the question is pretty vague.
Also, just about every car back then used similar seals so if you search youtube, leave out "early A bodies" in your search if for example you are trying to replace wing window rubber.
This video is not for a mopar but it gives some great tips on adhesives and to be honest, most cars used similar technology on seals so it may be all you need.
