    "abstract": "In this paper scattering equivalences are used to simplify current operators\nin constituent quark models. The simplicity of the method is illustrated by\napplying it to a relativistic constituent quark model that fits the meson mass\nspectrum. This model requires a non-trivial constituent quark current operator\nto fit the pion form factor data. A model with a different confining\ninteraction, that has the identical spectrum and can reproduce the measured\npion form factor using only point-like constituent quark impulse currents is\nconstructed. Both the original and transformed models are relativistic\ndirect-interaction models with a light-front kinematic subgroup.",
