just build some new ones out of square tube... shouldn't be too hard, just make them the same length. i don't know why you would want to reinforce the crappy stock ones when you could just make new ones super-easy. i never had any problems with my factory ca's, they took such a beating. but now, if i was to upgrade them, i would just build new ones.
just my thoughts,

p.s. you should just take them off, all they do is get in the way...right hahaha
