"went to quadratec.com and found that the tops for fulldoors has a different order number but only by one x..........."
Yeah, my lottery number matched all but one digit,too!
Man, it really depends on the top she is selling. Some tops use factory hardware and some tops use their own hardware. YJs are different than TJs, and Limiteds are different still. You better research it thoroughly or you may end up with a top that you can't use.
