I can't tell from the photos but if the seal dimensions are marked try getting replacement based on size from a local bearing/seal supply store. If they are not marked get out the calipers and measure them. I'd almost bet if you walked in to such a supply store they could find replacements.
As far as removing seals without damage it can be done with proper tools. Prying seals out with a screwdriver always damages seals beyond re-use. You may be able to get these fairly straight to use them again but they will not do their job very well.
Good luck,
