Just completed first oil change on my 06 ST1300. Started on the final drive oil change. Drained the hypoid gear oil and replaced drain plug. Attempted to remove the fill plug bolt and the threads broke off from the fill plug and I had to use a screwdriver to unthread it from the drive case. My question is, where would I find a new fill plug bolt? I'm attempting to JB weld it. I'm assuming that the last time the drive oil was changed by the previous owner they weakened it when installing it. I didn't use hardly any pressure when removing it. Any help would be greatly appreciated.
