Replying to Heel rip out after heely coil

So I've got a pair of surface green lifes with fks 120 bindings and managed to pull out the heel piece when mounted regularly and again after having the screws coiled. I'm curious if these things are pretty much fucked now or if there's other options I could look into. Remounting farther back apparently isn't an option that any ski tech I've talked to would do. Just seeing if I can milk any more time out of these things
