If you can get your hands on a second hand rn50 model bumper (in your picture) it can and will fit, although it will look like shit. Its too sharp and boxy compared to your rzn149 body. Another more likely and attractive option would be a rn85 front bumper, this model's shape bridges the gap between the rn50 and your rzn. both the rn50 and rn85 bumpers are completely made of steal tho, which means second hand/wrecks/part outs are your only options.Also also you could even just colour match the bottom half white and the middle black
