My friend crashed my Banshee and damaged the upper "A" arm on the left side. I don't know if the lower is damaged yet, but now is a good time to think about aftermarket parts. What kind of aftermarket "A" arms are best and why? Has anyone been able to find just uppers? I'm really uneasy about getting used ones since I don't know what they've been thru. Of course if I could find some that were new that were taken off when the bike was new I'd probably consider that. I have a 99.
