here is another crazy IDEA just to have in mind LOL
if things don;t go well with UPS and you DON"T want to get a different stock' maybe find a good stock worker and have them add a pistol grip CAP to the stock to cover up the damaged area
can have it customized to something maybe that means something to you, or just a customizes touch to things
this way forearm and r ear stock match better and damage is unseen again!
food for thought, cannot see it being that large a deal for a good stock worker to correct here with a nice cap!
could be as simple as this

or if your handy and want to do yourself?? second video shows maybe a nicer brass one, plays after this one did
and or??
maybe can make one you want?/

or again, something fancier, have to be fitted and mounted, but, maybe a better way to resolve an issue than mis matching a stock set!
