The axle will be crooked as was pointed out earlier, might cause some tire wear. It's hard to tell how much without throwing it on an alignment rack, but I'd try to get a replacement sooner than later.
For what it's worth, I reinforced my lower links after I replaced them with some new-ish FJ Cruiser ones that had 20k or so on them (customer gave them to me, didn't need them when I put in aftermarket ones for them.)
It took some patient stitch welding and some cheap angle iron from home depot.
I mentioned the modifications in my build thread,
