Two ratings in one

First is for the actual book: It is clear, uses dark lines and sharp figures to present the diagrams for the vacuum application being worked on (or studied). An awesome resource for the pesky vacuum leaks I HAD. Most the Shelby/Mustang stuff seems the same as the Cougar and I have not run into any issues troubleshooting the system.



Second rating:

The free "Vacuum Schematic for the Cougar Vacuum Headlight System" is just a extra photocopied paper. A poor photocopy like the printer was low on toner possibly. I found a better one on the internet (not good but better) that I printed out on high contrast to use) I'd give it 2 stars.
