Can they only fit together one way (tops have to fit to bottoms?) or could two tops fit together? Second part of that question are they different widths?
It's a oct 2010.
They should be colored, not entirely of course, but there should be a little area with a colored marking. Or else if some are marked 702 and some 703, that should differentiate them for you. Or are you saying all of them have "702/703" on them?
Either way, it is absolutely possible to install them backwards or install two tops or two bottoms together, and you do NOT want to do that.
If all else fails, you can get a micrometer to check their thickness against the measurements that have been posted in here somewhere to find out which are which.
