you can put the bolt in the end and use a ratchet and socket to spin the crank
Actually, I just realized... I'm a dumbass!
There's two flat spots on the accessory pulley from RK Sport (and maybe the stock one?) so you can put a wrench on it.
I didn't want to torque down too hard on the end bolt. I was worried about breaking the threads.
