A friend of mine wants to restore a Lionel 8203 for his daughter. We think the e unit may be worn out. If so, how difficult is it to find a replacement? As I recall, this engine has the kind of e unit with the black lever that moves back and forth, not the silver one that moves side to side. All the e units I've seen on evilbay seem to be the ones with the side to side lever.
Thanks.
