Here is what I have used in the past. Clean the area very good with a wire wheel on a drill. Clean the bolt the same way. Then clean the area and bolt with carburetor cleaner and use compressed air blow out the excess and dry it out. Next, use Q-tips (you will use quite a few) and rubbing alcohol to clean the bolt threads, area, and bolster threads until there is no dirt that shows on the Q-tips. Then take a traditional car wax and wax the threads on the "bolt" only. Hand tighten the bolt into the bolster threads until it reaches the end. You may then mix up the traditional slow cure J-B Weld and repair the area. Please allow it to cure completely 24 hours etc. The car wax will keep the bolt from sticking to the J-B Weld while copying the threads. You may need to take a wrench to break it loose but it will back straight out. This process may be used to repair the drain plug in the bolster as well as many other applications. Hope this helps.
BTW, in the words of Randallc "Clean Means Clean"
