I just installed a new recoil lug from Northland and discovered it is longer than the original and won't fit in my H-S precision stock. What should I do?

1) Cut the recoil lug and leave stock alone? or

2) grind on the aluminum inside the stock, leave the recoil lug alone and use devcon to bed the recoil lug area?

I leaning towards grinding on the stock and bedding only the lug area. I'm just a little worried about deepening the lug area and grinding through the aluminum and leaving the forearm portion less supported.

Surely someone else has had the same dilemma and found the best solution. Thanks in advance.
