I assumed the tubes ran all the way through the body. I'm very surprised to see them so short. My 1st introduction to drain tubes came through our 2001 Caddy. The sunroof kept leaking. After digging through some forums I discovered the drain tubes where backed up. There are 2 tubes that run from the roof down the pillar and out the fender well. I'm going to do the same thing with my 59. I will run the tubes out the bottom. I'm about to start driving it all the time so rain will be a problem.
