Welcome, The bolts can be straightened and reused. Just bead blast them and paint. The version you have does not use trim around the adglass. It simply is pushed carefully into place and the flexibility of the bolts hold it. I use a bit of clear silicone at each bolt/glass point to be sure glass stays put. I'll have two of these posted on my web site in a few days under Currently Available and For Sale. We did one each showing the trimmed adglass and the non-trim. We have the window rubber in stock along with other parts you might need? Best regards, Paul
