I've got a ragged PPI PC21400.2 in for salvage if possible. The thermistors are broken on it. All but the one in the center of the transformer and one for thermal bias(this one I can pull and measure). If anyone has values for them it would be an excellent help.

This information may prove useless. Someone else may have more definitive answers. These are from a PC2300, in the circuit and at about 65°F.

Back on this. I figured I would post the information on the part I was asking about. They are a 50kOhm NTC thermistor, DO35 package.
Back on this one. The physical damage from shipping has been mitigated.
The turn-on circuit was thoroughly damaged. All the way from the positive control through to the negative control ends. Two A56's, one A06, one A13, one 10ohm resistor, one 0.1uf capacitor, and one 4N25 opto-coupler.
The power supply was cooked as well. Both 4080's, all 16 power FETs, one trace, many hot areas on the board in the supply area. I think this was caused by leaking capacitors and/or poor vehicle electrical.
There was a failed repair attempt before it was sent to me. It appears the tech replaced all obviously bad parts and it wouldn't power up so was abandoned. It will be an expensive repair but I am now confident that I can do it. Here's hoping other's have success as well.
