Hardtop Roof Rail Weatherstrips - 66 Dart hard top

Looking for new roof rail seals, a couple of places I checked are over $250 for both. Seems way overpriced to me. Does anyone know of a more economical resource for these seals? These are the seals that the windows rest against at the top to seal out water. $250 seems ridiculous I just got a quote for new leaf springs, and all hardware for less than $350, I ain't paying 250 for some rubber.

Thank you.
