FIRST is not perfect all the time, I remember being caught by inspectors because our bolts for our wheels on the c-base extended out past the frame (now they have the 1/4 inch policy). Well an easy way to fix this would be to cut some longer pieces of c frame that are 1 inch longer on each side so you have the frame mount nicely and make a 90degree corner. This may work for your front since those are probably short pieces anyway. But the back piece seems like the max dimension for a c-frame. Well, is it feasible to slide your outer two pieces in one hole? This would make a 90degree angle, but I am not sure how the internals of your ball manipulator and shooter are put together. If not look into adding something to fill that gap.
