"I had the same issue with my truck. Some idiot put metric bolts in standard drilled holes on my front dif...it leaked and filled with water. All the holes were stripped. I had to have the dif pulled out, cleaned, and pretty much rebuilt."
Easy enough to do as so many vehicles use a combination of metric and standard, but if the bolt doesn't go in easily, hey , maybe it isn't the right one. No big mental leap there! Too bad some people can't even make the small mental leaps...like across a synapse...
One of the reasons to just not toss bolts you take off, but to keep them in a nice neat area...or make a cardboard template for them. I have known too many people who work on stuff that do this and it always involves many needless trips to the auto store or hardware store to find the right bolt...I refuse to work with people that do this...
