I'm ashamed to admit this, but I've chewed up the thread on one of the body mount nuts. True to Sod's Law, it's the position #2 nut (#1 on the main body), which is enclosed in the box section under the front floor and is totally inaccessible. I thought that the stiffness while tightening the bolt was a combination of paint on the thread and rubbing due to slight body misalignment. Turns out the body WAS correctly centered; the nut had just moved slightly in the box section. Looking at the bolt, it looks like the ridges on the nut have cut into the ridges on the bolt, parallel all the way down to the end of the thread. I'm kicking my own ass for not double checking everything and being more careful, but what's done is done, and now I'm wondering if anyone else has been through this and/or can offer advice. I am dreading having to cut through the floor to get at the nut and bracket that holds it in place, especially as there are multiple spot welded reinforcement layers there (and because of all the time I spent welding the holes in the floor CLOSED!). As the thread is not completely stripped, is there some way to salvage the nut? I took the bolt out of the other side and did the same to the thread on that, but it tightens up and seems secure. Is there a chance that the thread will be ripped out completely while cornering hard, or will it be OK left like this? Finally, I later discovered that the replacement bolt that I used from LMC is wrong. It is too long, and the thread is too short, meaning that it reaches the end of the thread before going all the way in. Also, all this trouble could just be due to a badly cut thread on the bolt. Does anyone know where to get O.E. type bolts from? Thank you!
