I put those pieces on as well over the weekend. Be thankful you don't have vinyl.

The left side fit "fairly" tight, and should only let in a trickle of water, but the right side has a large gap, especially under the curve where the belt trim should lay flat. That gap was disturbing enough that I put in a thin foam dam.
My drip rail on the right side was noticably wider than the left, in the area your pics shows.

It's no wonder some of these cars rusted from the inside out.
I downloaded some pics tonight.
Notice the rail width difference from left to right? I don't know if that has anything to do with my gi-normous gap on the right side, but I could
not get that thing on tighter.
twodko....I here what you're sayin'......but being able to see inside the car from there can't be a good thing.
