Antique Rheem Questions

NEW MAN HERE , I have a Rheem Mod 3402-110 furnace , it was totally rebuilt . When I installed it I broke the limit switch . Pretty sure it's a White Rodgers 5A75-10 , The outer cover was rusted and I can't get the # of it . I installed a Rockwell limit switch and it works but have tried different settings and it does not cycle right . I think the insertion probe is too short on the rockwell

and not reading heat correctly . Is there a way to search my Rheem # to see if this is what limit switch they used (parts diagram)? I think I can find a new/used white rodgers but I am not sure where the probes are located . A Rheem manual/diagram should help me locate the 2 heat sensor probes . Also the one probe is broke but it unscrews so maybe I can find new/used one ? Thanks

    You installed a "Totally rebuilt" warm air furnace? Rebuilt by whom?

    Do you have hard wired CO/Smoke detectors in your house?
