I used needle-nose pliers to bend two horns back into place. I first covered the plier jaws with electrical tape so I would be less likely to scratch the horn assembly. I applied a small amount of torque and the metal slowly bent back to a more normal position. The amount of force needed was below any concern over damaging the plastic. I purchased the F-3 set on eBay and they arrived today. I've attached before and after pictures for the two bent horns. Tom
