Thank you for the help! I’ve been looking for one and this will help.

When the M70 was introduced, the scope sight was not in wide use and those that were in use were mounted high so the M70 safety was not a problem. As scope mounts became lower, using the original safety was hard. Several companies offered replacement safeties such as Tilden. See the illustration below. Bolt handle alteration to accommodate the low scopes became common place. It was not until after WWII that Winchester offered the low bolt

Here are pictures from the American Rifleman magazine for November 1936 on the introduction of the M70:

This shows the original safety and bolt.

This is how my pre-war M70 target rifle is configured.
I have a pre-war sporter, but someone has had a late model safety and bolt plug installed.
The early Lyman 48 sights required a cutout in the stock for mounting
For RCS:
Your rifle is configured for the last model safety though I believe that it is an early post-WWII rifle. It has the "clover leaf" top tang so may be pre-WWII. My sporter has the same type of safety.
Here is another commercial safety for the M70 by Pachmayr. Looks as if Winchester may have copied this one.
This picture also shows the early bolt. From the December 1937 American Rifleman.

Here are some more pictures showing various versions. Sorry about the fold but my scanner does not allow too much of a fold on the book. They show some variation of the M70 over time and may aid you in your restoration effort. Early parts may be hard to find as not too many M70's were sold pre-war period. The bolt in the lowere left has the bolt stop extension for the .243..308 rifles .

Sight on left is early Lyman 48 and requires stock cut. Sight on left is post WWII and does not require stock cut. Both are labeled 48 WJS and both have 1/4 minute clicks

Is this what the tapped holes were for on the receiver I have? The holes are drilled on the right side of the receiver and I was trying to figure out what they were for.

[Cosine26]

No. The Lyman 48 and all standard receiver sights mount on the left side of the 70. Redfield & Vaver receiver sights all mount on left side of M70. There were many different scope sight bases designed after WWII. Those holes may be for one of those. I do not recognize the hole pattern.

I found a bolt for the barreled receiver and I held my breath when I check the headspace. Boy was I happy when it passed. Its a perfect match for my rifle and from looking online looks to be the correct bolt for my 1940. I cycles perfectly in the action as well.

Thanks for the help everyone, made looking for the bolt a lot easier.
