Mark II stock question

I recently purchased a mark II I believe G model with no accu trigger. I am curious if the stocks are interchangeable with the factory synthetic stock. I know there was a change in the size of the action in the past and don't want to buy one off eBay that I can't use. Unfortunately I am currently at work so I cannot measure which actions have or confirm the model. Here are some pictures though.

That will have the measurements you need to determine if yours is the newer E-type receiver or not. Basically they made the receiver 5/8" longer, but the action screw spacing appears to be the same. There are a few other noted differences in the stocks though, so a little modification may be necessary to make one work with the other.

Thank you
