It is proved that any A-covelocity T^A_x f in T^{A*}_x M is determined by its values over arbitrary max{width, diím M} regular and under the first jet projection linearly independent elements of $T^A_xM$. Further, we prove the rigidity of the so-called universally reparametrizable Weil algebras. Applying essentially those partial results we give the proof of the general rigidity result identifying A-covelocities with classical jets. We also introduce the space $J^A(M,N)$ of $A$-jets and prove its rigidity in the sense of its coincidence with the classical jet space $J^r(M,N)$.
