thank you for your comment.
i must explain: am not thinking on buying it right now. just trying to save time in case it has no corrosion.
i recall a discussion on the subject, and it was then that i saved the link, just to learn that is oos.
there are other packs available but are 3 points and this 1 seems easier to install, but if cant be found and there is no corrosion i will get other of 3 points that seem available.
the idea is to open it of course, but if it has corrosion i just will dump it and wont replace it.
but if i learn that it is needed for other purpose, that is, that if not installed it affects the performance or something else, i will replace it.
do you know if this is the case?
thanks again.
