Todd, no matter what type of butt plate and grip cap you get, none are going t fit perfect. They all have to be filed, sanded down to touch the wood. Not easy to do. even if you found a "real" set, they still wouldn't fit right. Hold on to what you have, go to Brownells or Midway and order what is close to your size but not under. I believe Brownells has a few different sizes, and also have some blanks. The holes c/c should be very close to 3". Fasten them on and scribe a line and around it. Be careful at the top of the stock because I believe the angle is -7 deg. and the bottom is +15 deg. Do the final filing and sanding with the butt plate secured to the stock. If the screws fit the counter-sunken holes correctly, you might be able to remove it and re-install it again, but not likely. Finish the butt plate with the finish you will use on the stock where you hit it with the sandpaper, file. Good luck.
