Water pump attaching to Slant 6

Good point. That bypass hose is a PIA. I still recall spending over an hour changing it in the college parking lot on my 1969 Dart 225. I suggest buying silicone hose (ebay), as I did recently for my 1964 225. It should last forever, plus looks cool in blue. It is more flexible, so slid on easy, which might even work on a 170. Use only silicone hose clamps (no slots that cut thru) and stainless looks smart. I use it wherever the hose is a PIA to get at.
