Drilled hole into the part of the broken bolt still inside crankshaft, I then heated the bolt that was still inside the crankshaft with a propane soldering torch and used penetrating oil to soak into thread and then used an easy-out to remove the remaining half of the bolt from inside crankshaft.
I then replaced the old parts with the new ones I had purchased from your company
