Degree bounds for projective division fields associated to elliptic modules with a trivial endomorphism ring

Let $k$ be a global field, let $A$ Dedekind domain with $\text{Quot}(A) = k$, and $K$ finitely generated field. Using unified approach for both elliptic curves Drinfeld modules $M$ defined over having trivial endomorphism ring, $k= \mathbb{Q}$, $A \mathbb{Z}$ in the former case function its ring of functions regular away from fixed prime latter case, any nonzero ideal $\mathfrak{a} \lhd A$ we prove best possible estimates norm $|\mathfrak{a}|$ degrees subfields $\mathfrak{a}$-division fields by scalars.
