Can a Winchester Black Shadow be converted to a bdl with a wood stock?

Are you asking if a Win. model 70 Black Shadow action and barrel will drop into a Remington BDL stock?

No, into a Winchester stock with a bottom plate. Are the parts like the spring and stuff interchangeable

Noone knows?????

They should be, I don't see why they would make the recievers any different for an economy version of the model 70. That would raise the price of the gun; the opposite of what they want to do to sell them.
