2005 Suburban BPMV motor removal

Has anyone removed the motor from the BPMV? My ABS was showing a C0267 pump circuit motor open, and lo and behold the wires were shot (totally corroded) at the point they enter the motor. Tried removing the pump and both bolts were frozen. The beauty of disimilar metals along with a splash of salt. GM engineering sometimes never ceases to amaze me. One I finally got off, the other of course, true to form, snapped. Anyone know if there's enough material to use a heli-coil? Any other suggestion to get the piece out?

TIA
