A lot depends on the curvature of the stock in the trigger plate area. I bend mine to fit and on some had a problem with double set triggers engaging each other. I ended up making a new rear trigger - after that no issues. You can bend it cold if not a lot of bend is needed but go slow and watch for colapsing of the trigger's "windows" - you can always file the window square again - hope this info helps - others may give better advise this is mine - good luck
.
Forgot to say if the trigger plate has enough thickness you can file it to fit the contour along with the bending to improve the smooth curvature of the stock.
