UPDATE - Guy that had the W/S gave me the part # "W523" from the box. This turns out to be an after-market replacement #, which I HAPPILY DISCOVERED was for 50/70 HTs & Conv (exactly what I needed!). I did a Google search to find this out, coming up with this from Auto City Classics:
1957-1958 Buick-Cadillac Windshield W523
Price: $399.00
Fits Buick Models:
57 2 Door Ht Riviera Series 50, Roadmaster 70
58 2 Door ht Riviera Series 50, Roadmaster 70
57-58 Convertible Series 50, Roadmaster 70
I paid $150, and it was located 10 miles from my brother-in-law, so no shipping charges. Sometimes, one gets lucky! Cheers, Brent
