any list of part numbers for facory spindles, rotors, calipers, etc. for building your own disc brake conversion for a 69 el camino, want to swap to disc on all 4 corners. Or is the concesus it's better to just buy a conversion kit? Thought about using drop spindles to lower the front a little, but a friend mentioned that he ran into problems with tie rod ends hitting the wheels using drop spindles? Maybe better to use springs rather than spindles to drop it a little?
