not sure but i think u can prally get one at ur local junk yard

 

Don't be concerned about what size it is, just go to your local dealer and buy one. The crank pulley bolt is hardened steel with a flange built onto it. It's not something that you can go down to Home Depot and buy. The last thing you want is for your dampner to fly off on the freeway at 70 mph.
