Yes, I agree with you there, it's a matter of faith.
So, what do you have? You have faith enough to stand up and proclaim that there is a "perfect" text which can be used to correct your KJV BIBLE, (and ours) but that "perfect" text is a text you CANNOT UNDERSTAND, DO NOT HAVE, AND CANNOT EVEN READ. This by your own admission is your final authority. That strikes me as a weak position, brother. You need to think that through. I think you have to at least consider the possibility that your faith on this issue might be in the hot air of scholars.
