part 1: for those of you who have taken apart the dash, is it difficult? can it be screwed up? did you notice any more/less squeaking or rattleing after you did it? any tips / suggestions / things to watch out for?

part 2: for those of you that have linearized the temp gauge - was it difficult? can it be screwed up? any tips / suggestions / things to watch out for?

i've seen the web pages for doing both things, just wondering if anyone had any personal experience in doing either of these.

thanks
