Rusty rear crossmember specifically the trailing arm mount. How best to fix this?

[DrieStone]

I've been doing some maintenance on my '92 Loyale and I've noticed the outer sections of the rear crossmember is pretty badly rusted (this is where the "trailing" arm connects to the body. I'm thinking I may want to do something about this before it fails. There's some body rot elsewhere, but overall the car is is decent shape. It has a lift and the rear tires are sitting forward so I should lengthen the arms as well (secondary project). It looks like only real purpose is to locate the outer bracket for the arm.

Not sure if anyone has fixed this. I'm thinking I'll cut the end of the crossmember off and fabricate up a bracket in such a way that I can get a good weld on it. I'm no expert, but this pretty much only carrying a front/back load, so I should be able to come up with something that works pretty well.

Thoughts?

Ahhh , I edited because I can see you’d likely rather keep this car than get another from out west. 
 

I’ll stop back when I’m more awake. Also in CT
