Where does the Chrome vinyl trim surround start>?

[72and86]

1970 Coupe w/vinyl top.
When I got the car someone put a screw right into the vinyl top chrome trim that surrounds the bottom vinyl on the sail panels and trunk extension panel. Im replacing the vinyl top now but where and how does the chrome trim attack correctly? I know clips hold the middle. But, How does the trim tip start (below the end of the drip rails).
This photo shows the rear sail panel on the drivers side. Left is front of the car. Is this factory with the rivets? Thx

The end of the trim almost touches the drip rail molding, maybe an 1/8" gap ? and the bottom of both pieces should line up

Looks like someone pop riveted your quarter panels on....that is not factory.

I replaced my roof and filler panel so I had to re drill the holes. I have taken photos of various challengers and noticed some had slightly different gap spacing between the window trim and the wrap around trim. I'll check to see if I can find those pics.

As Alan said, it looks like the quarter panels are at least just pop riveted on the top. You should do a close inspection of the underside of the car. There may be other poor repairs that could be structural and therefore very unsafe.

  Yeah, there should be a good amount of lead in that area. Not sure what would have been pop riveted. Seems odd.

dont put a new top over that mess

After you fix/replace the quarter panel(s). Here is some top hole info.

Thanks. Perfect!

I would add that besides following the dimensions, you test fit to make sure the ends of the trim end up exactly where want them. A slight deviation will show up where that trim  meets up with the drip rail trim.
