Upper spray arm screw broken

Dishwasher Repair

The 8-32 screw that secures the upper spray arm broke off in the receptacle
It is not listed on the parts lists as a replaceable item
I have tried to remove it unsuccesfully
How is this receptacle attached to the ceiling of the SS dishwasher

If its welded I’m out of luck and a 2$ screw will cost me a new unit
Any help is appreciated for this 1st time poster

               Thanks   Peabody

Thanks for the suggestion
I have already attempted,and failed to remove the broken part of the screw from the socket area
I guess my last chance will be to drill it our the same diameter as the I/S dimension of the spray arm bearing and try to epoxy a new support screw in this manner.
Again Thanks
