hi guys!

my b310 meters doesnt come with a tacho. i intend to get a used/new (if available and affordable) b310 meters with tacho. my question is, isit hard to dismantle the meters? i read before in other forums that its not that easy to remove the meters, and ive never tried it before.

secondly, the position that is supposed to be the tachometer in certain models is occupied with the temperature and fuel gauge in mine. will it have any effect on fuel, temp and etc. readings if the position is changed with the new meters? thanks in advance for your replies. cheerz!
