A buddy and I are making a drop-in stock system initially for Remington 700s, and expanding to other actions.

If someone has a 700 from the 70s, can they bolt into a stock just the same as one made yesterday?

Does the trigger assembly still attach with two pins in the same location? Can I put an Xmark trigger on an older action? If not, when are these distinctions made?

yes-- all the same. stock fits and trigger locations with .125 pins. I would assume the triggers interchange but haven't had had to do it.

Stocks inlet for the X Mark/Pro trigger groups are different from the standard pre 2006 trigger group.
Inlet for the std/pre 2006 trigger group will need more clearance at the aft action screw hole(safety lever)

Inlet for a Jewell trigger group will be deeper & wider than the std trigger group & bottom metal will also need minor machining.

.
I think the rule of thumb with the Remington model 700 is:

"The stocks made today, are backward compatible with the guns of yesterday. But the guns made today will not always fit in yesterdays stocks." Remington kept cutting away material as they needed to make run changes. But I can't recall them ever adding any material.

The exception to this is the Model 700 DBM, which has proprietary inletting for the magazine.

There may also be a difference in the Ultra Magnums. But I have never had a problem to date or actually had to measure them. It might be worth it to check.

Thanks for the input guys.

So the bolt spacing is the same, and if we used a different magazine system and trigger, we should be able to just have one inletting pattern?

Remember that the SA and LA are different in length.

I kinda left that as a given but that would be taking the obvious for granted. The XP, 600 and 7 are proprietary as well to some degree.

Is the 40X also a variant? Or is it simply a solid bottom short in the 40XB and Rangemaster? It seems to me that even the 300 Winchester in the Rangemaster was a short action. Or am I loosing whats left of my twisted, little mind?

Far as I know, all 40xs were/are short action.

Early and late model bolts were different. Early models did not have a guide rib. Late models did. Early bolts will not go into late receivers without a small modification.

This doesn't matter, he is only interested in the Inletting.
