As I have tim e I will be adding "built" information to a couple of other calendars Viper Build Dates and Viper Truck Build Dates. So each day you will be able to see how many Vipers and Viper Trucks were built on that day
Example

I only have about 27k more Viper build dates to get, so that calender will be way behind for awhile. The Viper Trucks, I have all of those build dates.
Enjoy
