Well about a year and a half later my dad s old 640 is about finished. Thanks to all here that helped and gave advice.
Before someone protest the color or the color scheme (I know it is coming) I just want to make it known that this was the way it arrived in 1977 and it only seemed fitting to keep it that was as that is all my wife, kids or myself could ever remember. The original color or color scheme did not look correct after seeing the tractor this way for so many years.
Finally it was decided that it was not about correctness to the 640 but memories of my father and their grandfather.
Once again thanks to all that helped and gave advice!
