I am restoring an 88 Sedan Deville. Just had the Headliner upholstered and want to install some of those plastic windshielf post, but I can not find any listed. Checked ebay, jcwhitney, all the regulars. Found some for Chevys but said it would not fit my caddy. Anyone know where I can find these? Thank you in advance. I am new to this forum and I must say that I think it is great!
