Broke the alternator tensioner pulley bolt "gusset" on my 98 Montero sport LS (3.0L V6) while attempting to loosen the tensioner pulley to replace the belt. This "gusset" is part of what appears to be an aluminum bracket that holds all of the tensioner pulleys (for the alternator, power steering pump and AC compressor) to the engine block, as well as the alternator and the power steering pump itself. Anyone know the part number and a good place to get a replacement?

Thanks!
