Just remember......crap happens. The "new" passenger window on my 37 or about 5 years suddenly cracked when my sister in law shut the door. Yep, all new stuff and never a problem and it still cracked. Didn't change anything but the glass and here, 10 years later and many "slammings" by a few un-respectful idiots and it is still just fine.....it happens Showme!!!
