This is great info! Now after reading it all it seems to boil down to the spindle and it being a mustang II style part, is there anyway to have a hub based version like a viper or vette (you get the idea).
if you mean of a purpose built front steer spindle w/ workable geometry (like widely used on a Mustang), most use it because of the availability/cost/multitude of brake packages factor....compare price ($169pair/new) to vette or viper parts and/or brake packages
