If your really concerned with tha bolt hole holding, test it first with the bolt torque down first after cleaning it up with a thread chaser tap. If you want to add a fix then look at buying and using Loctites Form A Thread repair kit I finaly remeber to go out in the shop and take a picture of one of Loctite thread repair kits that I have had hanging on the wall for years, maybe that help you The part number is 81668, it is intended to repair threads in place I've never used it, so your on your own
