Thanks DOCRON and yes, its for the bolts that screw to the tub. Would they able to give me the correct size tap and die if I take the bolt to a hardware store?Yup, you’re right... sorry, misread it.
There is a post somewhere in the forum about this specific issue, those inserts are commonly factory crossthreaded. 2 of mine were when i did seat swap.
Best solution is to retap insert. I want to say it is the same size but dont quote me on it, it is a common problem so much that it has its own section in the TechAuthority Service Manual. I had to retap my inserts. Do NOT force torque them! You dont want to snap off head off bolt while the bolt is in the tub insert. OR strip the bolt head!
Like i said, there is a specific tread in this forum about it somewhere. I posted screenshots of the tub insert from the manual.
