Help,
My '69 convertible has windows that go too far up, are uneven and don't seal with the back quarter windows or the top, they rattle , and I can't find weatherstripping that seals the top of the door to the window(there is space between the window and the weatherstripping), hence the rattle. Ive tried Johns Mustang, Year One, and California Mustang. Any ideas ??
Thanks

 

take off the panel, unbolt the window assembly and lower it to fit in place. i believe it's adjustable.

 

I Believe 1969 Mustang windows were glued in; in 1970 they went back to bolt in.
