Mike - The part # given is for a pair and I believe they are bent at the ends, although I have a pair with adjustable ends also, so they will work left or right. I dug up the paperwork and the pair I have here are #T-17527-3, LH, and T-17526-3, RH. They are "concours correct", bayonet end arms. These are $29.95 each, (60 bucks a pair) a bit pricey but really nice. The overall length of the arm is 12".
