This one makes the second headliner I have put in. One was in a 50 Chevy the other this 51. Both have the same problem even though almost 5 years apart.

The instructions said I would have to pull back the rubber seal of the windshield to let the liner go behind it, didn't even touch the seal.

Should be hidden behind the door trim/seal.... and in places not even close.

If I do another I will check with other places to see where they get theirs.

Thanks for the suggestions folks.
