I actually ended up doing this another way which was really easy.... the hardest part for me was getting the spring into the cradle. Once the spring was in the cradle I put the centerstand upside down and as close to the spring as it could get. I put the cs spring end right under the hole in the cs....so now the bottom is at the top. Pulled back gently while rotating at the same time, and the spring just popped in the cs. Then pulled back on the crossbar of the cs until the holes lined up, and pushed a bush into hold it....
