I have a Mesa Precision Altitude (RH / 13.5 LOP / Sendero contour) that was professionally bedded for a Defiance anTi XM and not really used. I purchased it that way from the original owner and never ended up using it myself. I know it's not what you are specifically looking for, but feel free...
I have a Hawkins BDL (Obendorf, not M5) bottom metal kit for a 700 SA with boxes and followers for both Wyatt's extended and regular length. It contains:
1. Bottom metal;
2. Action screws;
3. Spring;
4. Wyatt's extended and regular length boxes; and
5. Wyatt's extended and regular length...
