Need some help for specs on a model 10 FLCP-SR

[theflatlander]

looking at buying a model 10 FLCP-SR stock. Trying to figure out what action screw spacing this stock is? I am assuming 4.40? Also is it a bottom bolt release? Anyone know barrel contour/dimensions also? I want to mount a model 16 action to it, it's bottom bolt release, and eventually a heavy Palma or similar barrel

Thanks for any help.
