These bolts should also be relatively affordable.
Hope this helps.

Narragansett:
Were you able to solve your missing bolt problem? Since Winchester based its Model 54 action closely on that of the M1903, and their Model 70 being "bug fix" of their Model 54, I thought it a good bet that a Model 1903 bolt would fit a stripped Model 70 receiver were 1903's safety lug ground off. And then once a slot were machined on bolt face and frontal bolt body to allow the Model 70's ejector to function while using a Model 1903 bolt, your Model 70 becomes usable. Although dimensions were wartime sloppy compared with Model 1903s, an inexpensive 1903A3 bolt might be found - especially were you to be able to root through a bunch of them.
FYI: There is a superb book that may be available for digital download, U.S. Rifles and Machineguns, by Colvin and Viel (???) that identifies dimensions of every part of the Model 1903 Rifle. These dimensions are machinist's inspection drawings. You could determine whether a slightly altered bolt would fit your Model 70's receiver "by the numbers" without being forced to buy "a pig in a poke."
