When using one piece Model 70 drop box bottom metal,.375, without an attached box, what box do you use?

Pennfly,

Who made the bottom metal? I had no idea Winchester ever made drop box metal, so am confused. If you have standard Winchester bottom metal w/o a box, I would think a standard metal box w/o a spacer would fit your needs.

If all fails, call Duane Wiebe, Sunnyhill, Brownells or the company assuming Blackburn's company, Swift, I believe.
I have been wrong before. Call home and ask my wife.

Luck,

Stephen

Sunny-Hill uses a factory Win box, shortened about 1/8 inch.
