Okay after research turns out Snow Sultan was awesome and made the original template and it is still available through Snow Sultans website!
If you go down to near the bottom is the "clothing" section and you can find the MFD seam guide there, it works fine for Genesis and V4. There is a very slight gap along the shoulder seam, but is really really small and it should not be an issue when designing new clothing!
As I discovered when I used it, make sure you save it as a RGB .jpg before you start futzing around with it! The default color scheme is a .gif and is apparently indexed color, which does weird stuff and is not easy to work with!
