Quick question of OV-10D weapon loads???

I have some questions on OV-10 weapon loads. If anyone can help it would be a great help. Thanks in advance!

1)When the OV-10D Bronco is fitted with the 20mm M197 three barrel cannon can it still carry stores on the fuselage? Can it still carry the four 7.62mm M-60 machine guns or do those stub wings that hold the four M-60s have to be removed when the 20mm cannon is fitted? How many hard points can be used when the OV-10D is fitted with the 20mm cannon??
