I have a 50-52 Pontiac Visor and I am looking for the attachment harware, so I can put it on my 52 Chevy. I have checked National Chevy and Obsolete Chevy and have had no luck. It has the three small holes on the drip rail and then the clamp for the Windshield center bar. Any help would be greatly appreciated.
Try eBay or a Pontiac restoration business. The fact that you want to put it on a Chevy doesn't matter (it's the same body) - you need the Pontiac brackets.
i set it up on my 51 chevy, and it's too wide. looks like it should work, just too wide. i figure it's something gm, just not sure. didn't know if someone might recognize. maybe mid to late 40"s?
