I have a stand made of 80/20 aluminum that has top.  My new aquarium has a center overflow with two drains and two returns pre drilled.  I placed the aquarium on the stand and marked the holes. I wanted to confirm the bulkhead nuts and the 80/20 frame would not be in conflict.  Sadly, it looks like I have a problem.  The nut on the larger drain bulkheads appear to overlap the frame.
Any ideas of how to rectify this situation are appreciated.
