I am in the process of assembling the doors on my '65 Mustang. I ordered new vent window weatherstripping for each side. I bought the parts from CJ's Pony parts. The vent window rubber weatherstripping attaches to the metal part of the vent window assembly with some small brass "Brads"? that are included in the kit. One side of the brad has a flat end, and the other end needs to be flattened out to firmly attach the rubber part to the metal window frame. I have tried all kinds of methods to flatten out the end of the brads, but all I have been able to do is destroy a handfull of them. There has to be a tool that will accomplish this task. Does anyone have any ideas, or has anyone else ever re-done their vent window assemblies?
