Somebody ought to do a plastic replacement like they did w the 1022. Dunno how touch printed stuff is.
Id get the upgraded housing and have williams machine receiver to fit.
Im no machinist but worked w a shop many times and its IMHO fixable. Either mod old part for beefier new style front or get a new style housing. Either way the receiver will need modified.
Its just a matter of cost.
Somebody thats done it before can do repeats quicker.
Competent new guy? Proly take a few hrs at 100 bucks an hr
