Olds luvr

Well the car is now back together with just a normal purrrrrr to her. What had happened and I do not know how or why is the original shear pin (key) for the ballencer wore down on the edges and became a little sloppy and eneded wearing out the groove on the ballencer with a weird angle and was no longer squared. I will post some pictures of the key and the ballencer as well as updated pictures of the car....

Thanks for all of the replies guys!!!
