Diferences between T-72M and T-72M1 turret?

I’ve heard somewhere that the Tamiya’s T-72 hull is a T-72M1 hull, with extra armor in the glacis plate, but the turret is a T-72M turret, and such hybrids (T-72M turret in T-72M1 hull) never existed… Well, I’m modifying the Zvezda T-72 hull into a T-72M1 hull, but what about the turret?.. I want to know the differences between T-72M and T-72M1 turret, so I can make an accurate conversion for my Asad Babyl… Thanks in advance. Most regards.
