I'm getting ready to install the new window channels in my 51 chevy. The new channels that I ordered came with some clips that are different from the old ones. As far as I can see, the clips will not work. I contacted the company and they said they included tiny sheet metal screws for use where the clips would not work. the screws will work perfectly for the fuzzies but I'm not sure about the channels. What has anyone else used when installing the channels?
