You will see a number of drillings with bolts through the heads of the stocks to repair that problem.
they also might be able to heat it i oil and bend it back like they bend stocks to change drop and cast.
Stock replacement is quite expensive.
I bought a drilling the the whole head was shattered, with pieces missing and glued it back together, making and fitting the missing pieces and re inletting the locks to the new replacement pieces.
My old boss used to say "We do the difficult jobs, the impossible ones are just more expensive".
