Does anyone know of, or have a drawing for the pre-HE V12 bolt pattern?

It's the same as the HE bolt pattern. Only the dowels differed between BW and GM auto gearboxes. The 6 L block was different, but any esrlier bell can still be fitted to a 6 L block as the previous upper left bolt bosses are still there and just need drilling and tapping.

Thank you Peter!
Then my question should be:
Does anyone know of or have a drawing of the 5.3L V12 bell housing bolt pattern showing both HE and Pre-HE dowel positions?
