It has to do with the shape of the toilet bowl. I am not sure about the K7671 but the K4636 is for an elongated toilet bowl.
Easy answer is to Google your question and you will see simple illustrations of how to measure. I have attached a screenshot to show how. Hope this answers your questions.
No, unless you can use old hardware.
if you see them in the store you will see each has a slightly different design. one is a Reveal the other a Cachet. you can't really see the difference on line
If you're plus-sized, I'd stick with either a solid wood seat or one of the higher end plastic ones. I'm not that heavy but I broke one of the MDF ones by letting myself plop onto seat. Oops!

No, it is plastic.
