You could try JD fabrications, they are down there. I dont know if they will be interested as they are more of a race shop, but you never know. They make some pretty insane stuff, top notch.
Also, Demello moved to Corona a while back. And then there's T and J in Orange.
I dont recomend OutLaw Offroad almost just on principle alone, and they did a bad job on my brothers truck. But Im sure they dont f up everytime
But, have you made up your mind you want to ditch the xreas? I recomend everyone do there on bolt on work. Its not that hard, you have a wealth of information here at your fingertips. Plus then you will better understand the workings and troubleshooting.
my three cents
