WTB: windshield - '69 Valiant 2-door post

Need a windshield, new or good used. I believe the model number is DW-691 which interchanges with DW-857, whatever that means.

I don't know if a 4-door windshield is the same, or if a Dart or Swinger windshield is the same either, I really don't know. I've read many different opinions.

Will pay good money, need it asap. Shipped to upstate New York where I will drive from Canada to get it.
