''I'm going to fix it up someday'' The resurrection of a '74 Dart Sport......

One last thing before you buy a clutch fan... do a little junkyard shopping and grab the electric fans off some of the new stuff. Some of these move enough CFM to power an ultralight aircraft! There is a post here today about using a Ford Contour fan set up, and I've read a Lincoln Mark 7 has a very good setup. The whole thread is good but here is the post about the fan. In a 74 Duster so it should work for yours too.
