Hello. I have a used front windshield from a 57 Buick Super 4 door hardtop. It will definitely fit a 57 Super and Roadmaster, and MAYBE some 58's. I am giving this thing away at 150.00. I can ship it UPS, it won't be cheap. I got a quote to the middle states of APPROX. 150.00. If interested, please let me know, reply here with your zip and I will get you a closer quote. Thanks, Jeff
