82 Front Crossmember Information

[Stepsideblues]

I'm tryin to figure out the best route to take on my front end. It's an 82 c10 I'll be doing an las swap on.The front crossmember is separating at the edges and will need replaced.The right lower a arm is about rusted out to where it's surprising me the spring is in. I'm having trouble finding the lower control arms as replacements. Has anyone used an aftermarket crossmember ? Any advice would be appreciated.
