The opposite actually. If made for a mid plate, the snout would have a spacer and would either have been sent with spacers and or thicker pads. Both of which would space the core from the flexplate bolts. Remember, the flexplate is where it is and the converter has to be engaged in the pump lugs. So with a midplate the whole trans is back further and converter has to still engage lugs. This creates space between converter and plate so you fix it with longer snout and thicker pads.
