My 15 year old son is building a 68 Dart

Hi FABO
My 15 year old son is building a 68 Dart. My husband passed away in June, and did not get a chance to finish the car with our son. We are so thankful that someone from FABO sent us a lower controller arm, but unfortunately, it was for the passenger side. We are looking for a lower controller arm for the driver's side. If anyone has any ideas, please let me know. Also looking for the best place to find the "triad" emblem for the trunk. Thank you in advance!
