66 Convertible front roof seal question to stop leaks?

[Edz]

(sorry, moved to here, realised it was in the wrong section).

This are some pics of the front trim and rubber on my 66 convertible and it leaks, obviously because the seal is under the vinyl and the PO never trimmed the vinyl back?

Two questions:
1. Do I just trim the excess off the vinyl?
2. Is that the right seal or is there meant to be a thicker one there? The seal feels fairly soft still and has some flex.

I know I can tighten the lock-down clamps but I don't want to do them much tighter as they are already pretty tight. Once I trim the vinyl, I can tighten them up again.

Thanks for that 67FBGT. I'll see if I can find some pics online or a manual that shows the details better. The other option is to wait for a car show to check it out.

Hopefully someone will post some pics of what it's meant to look like as I understand your explanation but a picture paints a thousand words.

Cool, thanks Scollist, that's a great help, i wasn't sure where to start looking. I appreciate the help.

The second video showed most of what I need to do to fix it. I had a look at mine and the PO hasn't finished it there. They stapled under the top layer but it's not holding to the tack strip so I'll go visit an upholsterer when it's back on the road and see what they say and get a quote to finish it.
