Advice on Radiator overflow tank on 78 C3. I had to order a new tank as my original one started leaking after the A/C was worked on in that area. They had to replace the drier which sits beyond the tank. But for the life of me, I do not see the screws that attaches the tank. I can see one screw thread and a nutclip with a flashlight and mirror. How many attachments are there and how do I access them? This looks very difficult to me.

 

I did one on my '73 a couple of years ago. It wasn't as bad as it looks. I don't remember the details but once you get the new tank you'll know where the mount points are. If I remember correctly the whole job was less than an hour.
