Anyone have any spare REV am-2901 extrusion pieces? Also, mentor trouble.

After our competition, my team tried to see how well our robot worked after some modifications. We have to present it and the team to a full faculty meeting at our school on April 13, however, while picking up totes and cans, the line for a pulley system snapped after some misuse and the fall made critical sections of this http://www.andymark.com/product-p/am-2901.htm unusable. For three weeks the team tried to get our mentor to buy replacement material but he kept procrastinating and now it's out of stock. My team is in the New Rochelle area and we would be extremely appreciative if anyone would be willing to give a 6' or two 3' length. Without it, the robot cannot perform, and without a good showing, our team will likely be forced to continue to be regulated to a library for a workplace, and stuck with that one mentor. On a side note, does anyone have any experience on how they would go about replacing a terrible mentor that the team depends on? Any adult who just sat there during meetings and ordered for us the parts we needed would be better. We have evidence of multiple conflicts of interest for him, like when he tried to get us to funnel money we sorely need to his girlfriend's school. Also, we have thousands of dollars missing from the treasury which we can only guess what happened to it.
