I’d send it to Lee Christiansen(Redneck). Have him rebarrel it. Call D’Arcy Echols and see if he has any LH Legend stocks....If not he can order you one from McMillan.
Lee will be able to get that rifle shooting sub moa.

I’d cut that 26” barrel back to 25”(will look better than the 24” in the Legend stock but won’t be as cumbersome and will balance a little better than the 26”).

Nothing quite like a model 70 if that’s what you truely want.

I’ve got two LH Model 70s in Legend stocks. One is a factory barreled stainless 7mm Rem Mag. The other is a custom barreled 30.06 that Redneck rebarreled for me....It has a favorite load using a 165gr Nosler Accubond that’ll put 3 shots into 0.5” all day long, but shoots most everything I feed it MOA or better. Barrel is a 25” Pac Nor #1 contour.
