I took measurements of the inside of my case and put together some drawings. I hope I have given you enough to sort out the rest, but if not, feel free to E-mail me for addition dimensions. I didn't detail my spade grip mount as my grip is unique.

Tips:
If you have a carrying handle on your barrel shroud, make certain that the center brace on the lid does not interfere with it. I got a carrying handle as an afterthought and I have to loosen it and rotate it to make the gun fit. It's no big deal, but something to think about.
I mounted my shelf high enough to use the lid to keep things in place.
You can pad the surfaces with anything, or nothing. I used leather because it holds grease well.
Make certain the hole the booster slides into is deep enough for both the longer and shorter boosters.
