The pre-64 Model 70 Actions were all the same length and the magazine box, follower, bolt stop, and bolt faces were of different sizes to accommodate the different caridges. The 300/375 H&H's had a milled out receiver to accommodate the longer H&H..

Post 64 Winchesters prior to the the early 90's or so, all actions were all the same length and dealt with different cartridge sizes same as the pre-64's, but the same action was used to handle the H&H with no milling required.
The post 90's versions were available in short or long action, and push feed or controlled round feed. To convert to a 300 H&H from any post 64 long actiion with a magnum bolt face you will need a magazine box, follower, and bolt stop to accommodate the 300/375 H&H. These parts should be obtainable since the 300/375 H&H has been available in the post 64 Model 70's.
