Re: bottom metal for tacticool savage mkII
The Boyd's website now lists the part numbers you need to order from Savage. I just did this last week and it worked fine. Don't bother buying new action screws (I got talked into it), they're exactly the same as what you have. At least, they were for me.
As for the thicker bottom plate, that's one solution. My plan is to bed the plate I have. Even without that, I was able to get sufficient torque.
The rear screw on the trigger guard is a problem. Savage sent me a tiny little woodscrew for that, and it was way short. I had something lying around that I used, but you might be prepared for that.
