It’s a bit hard following along with all of the problems you have had… but that appears to be a picture of a pretty standard Klixon phenolic motor protector that is typically found inside a thermally protected motor. BRJ30DB = 1-1/4” diameter round base with solder connectors and will trip @120°C +/- 5°C (the “30” is the heater size, and is based on motor current rating). It should not be that hard to find a replacement (you could start by contacting Sensata at the link above to see if they sell directly or will give you a list of distributors).

However – your starter also appears to have thermal overload protection, based on the picture of it and the wiring diagram you showed a few posts ago. If so, then you only need one or the other, not both. If the starter has the correct heater for the motor, then you can bypass the klixon in the motor. If not, then you could try to find the proper heater – or you can replace the Klixon in the motor and bypass the heater in your starter (just jumper it with a piece of wire).
