There is always gonna be guys that actually "restore" the original iron.

And

There is always gonna be guys
that toss the original & take the easiest & cheapest way out.

Hell, you can go down to the "Truck Shop" & buy the whole truck piece by piece in cheap Taiwan pieces if thats your style.

Most discerning restorers I deal with will not even consider bolting parts made in the orient on an old America Bolt.
NOS & good used original parts are the only accepted form of parts replacement with this crowd .

Different strokes for different folks.
