Cool, it is always good to find color correct parts.

On the fan clutch, was it changed due to being bent?

Does this engine use a fan mount like a M104 gas 6 cyl uses? ( The fan is mounted to a bearing then a housing holds a bearing )

If the fan clutch took a hit, it may have pushed the bearing back in the housing or the fan hub back on the bearing. Take a look at the fan pulley, see if the belt has to bend back a bit. Also take a straight edge from the fan pulley to the next pulley and see if it is out of line.

If it is out of line and the mount isn't cracked, I'd end up shimming the fan mount bracket or put a shim behind the pulley so everything moves out. You could use a puller to bring the hub forward and / or remove the mount and press the bearing forward but this places more movement on the press fit parts and they might be on the loose side.

The other issue with the fan bearing taking a axial crash hit is that the bearing surface might be brinelled ( balls have dented the race ) . In the short term it may be quiet, but it might get noisy as time progresses. Was the bearing smooth to turn?

Fixing the ears can be done with epoxy such as J B Weld , but some plastics have low surface energy ( Tefflon for example ) and epoxy won't work so well unless there is a mechanical means of interlocking the epoxy to the surface. Take a look on the part for a plastic type code. Look for something in the format of > ABS < . 3M does make adhesive for low energy plastics but, it might be hard to get.

Look up Motor Guard Plastic Repair. They make a hot staple kit ( ~ $ 100 ) that fits on a spot welder gun. I'm realy tempted to make a low voltage / high current power supply to use it as a stand alone tool. Others make similar kits as well.

If you use the hot staple repair, be sure to seal the crack with epoxy to prevent water from entering.
