That will be a great great great help H.C, if you still have the crank shaft please do let me know.
I spoke to my garage guy and according to him, the crank shaft has to come out of the engine anyways, either to be repaired or replaced. I'm not sure how they are going to re-thread and how long it will last, so thinking about going with replacing the crank shaft, along with the crank pulley, key and the nut.
