yea i saw those and ended up making my own diagram if u go to this site http://www.atlanticz.ca/zclub/techtips/ you can download the diagram for your year and then load it up in photoshop and save it as a jpeg and load it up in paint and print it out over like 17 pages and then take the time to cut them all out of the pages line them up and tape them together. was thinking about getting them laminated as well. i did this for the 78Z and the 77 cuz the 78Z is blurry and not in colour and the 77 is nice and in colour, so the 77 is for cross ref when i cant read the 78 if it seems similar. also i did one for the 81 zx.
