I called Rem a few years ago wondering about putting a 7400 stock set on 750 when I was putting together my project 358.
Rem tech service told me the 750 and 7400 stocks/forearms were not interchangeable at all.
I had both stock sets in my hand, and I could see absolutely no internal or mounting differences.
The 7400 stock set works just dandy on my 750. I have no idea what Rem tech service was talking about.
