The H-D billet headlamp shell looks great but 300.00 WOW! I looked at Eastern Performance they have smoth headlight 5.75x7 Tri Bar for 100.00.Why so much cheaper? Custom Dynamics has a 5-3/4 headlight as well for 200.00.What is the best choice for quality is the 5.75x7 and the 5-3/4 the same size headlight? Most importantly will it fit a '07' Train and is it the same size as the H-D Billet headlamp shell? I am so confused I would like to save some money going with Eastern or Dynamics please enligthen. thx
