Savage Model 210, 12 gauge action question

I have a Savage 210, 12 gauge, bolt action shotgun. The action screw spacing is close to 5.05 inches. The barrel diameter near the breech is close to 1.12 inches. The barrel nut looks like a large shank nut but the grooves are a bit narrower than the grooves on my large shank Savage MLII muzzleloader.
I would like to get an aftermarket stock for the 210. I think a 110 long action stock would fit and be correct. Please advise. Thanks

This is one Fred (sharpshooter) is probably going to have to answer. I know the 220's have the long action screw spacing, and the newer 212's might be the same as the 220's, but not sure about the older 210's.

Here's a photo comparing bottom metals for a short action, long action and 220.

I hope SSS sees this and can reply. I could PM him directly. Thanks
