Look on page 42 or 3-2-28 (manual page number) of the CanadianNo.4 manual below:

You will see that you are to stake the receiver to lower the sear to keep it from hitting the locking lug. Only a Bubba or a (expletive deleted) would grind the locking lug down to make clearance.
The manual also states that “both” locking lugs should be making equal contact with the receiver lug areas, (no percentages of contact given) so just make sure you have enough “meat” left on the lug to ensure proper support.
And to think it was only yesterday I watched a Red Green episode where they cut the roof off a K-car and made it into a convertible and only used two rolls of duct tape.
A photo of the butchered locking lug would show more than our psychic vision and imaginations do for us.![]()
