this does seem strange that ev100 -parts- would not be available from SMH/TVH and/or Flight Systems, or the OEM.
is the problem that you only have the GE numbers?
what make model and serial number truck are you trying to fix?
is this "thermal protector" the temp sensor mounted to the #1 rec? (hyster PN 368920) or is it the insultion that goes under the rec or the heat sinks?
is the transformer the big block that has the EV100 sticker on it? (Hyster PN 368912)?
be sure to use thermal transfer grease when mounting new recs and transformer (Hyster PN 1198757).

I would guess I should not offer nusource as the place to find these "obsolete" parts...
