Vent Window Seal Replacement options

The vent window rubber seals on my '72 Dart have been cooked over the years and no longer seal to the doors along the bottom. I've poked around a few places and come up with wildly different pricing for a pair of these:

$80/pair:
Mopar A-Body - Dart Parts | MA2464 | 1967-72 Mopar A-Body Vent Window Weatherstrips | Classic Industries

$125/pair:
Vent Window Seal 67-72 A Body HT and FB

$250+/pair (be still my heart!):
1966-74 A B E-Body Vent Window Weatherstrips

Has anyone had any experience with and can attest to the quality of these or other similar parts? Or have a good solution for a different sort of fix? I'd love to not have to worry about water inside my doors.
