I have fixed cracks with an epoxy called Git Rot sold in Marine stores for boat repair. It is fluid and thin and is easy to get into cracks. Made by Life Industries Corp,N.Charleston SC. If it is possible to cross drill(1/8") the crack in the trigger plate inlet you could glue in some bamboo pins. These are made from shishkabob sticks bought from the super market. This makes the cross pins invisible and they are very strong in shear and hold to glue well. I did a Sterlingworth stock like this 2 yrs ago and it is holding up very good.
