You bought a cheap bar online. RC is known for having a LOT of stuff but they put their name on everything. The bars/kits they offer are just the cheap chinese style bars. Now. nothing wrong with those cheap chinese bars, you get what ya pay for, but they don't put the R&D into it like Baja/Rigid do.
Baja put the R&D into their bolt-on raptor kits and for good reason... because as smurf said, they work/fit.
Now.. how to solve your issue... well, remove the shutters. Honestly they can cause lots of trouble sometimes when you are trying to install accessories. Hell if you ever do an intercooler you're going to remove the shutters anyway, may as well do it now.
Or you can get rid of the RC bar, and do what smurf did... buy a Baja Designs kit (*cough* from us would be nice *cough*)
