I'm in the middle of installing new window tracks, etc. in my '56 Ford. I am going to replace the run channel in the front, butted against the back side of the vent windows. I got the channel and seals from Dennis Carpenter and they come with these itty-bitty brass rivets to install them. Does anyone have any experience with this type of rivet? They're hollow, so my first thought was to back up the head of the rivet with something solid, then use a center punch to spread the other, hollow, end. That is probably a bad idea, but I have never had any experience with anything like these rivets. I imagine other make cars used the same type of fastener, so I'm hoping one of you has some guidance you'll share.
