337 SN0127 Restoration

[GMPoland]

Need some help identifying a contactor on my fire wall. its not suppling power to any system and not in parts or any other documents I can find. Contactor is located on the center to Right side on firewall. Any Ideas?
Secondly: My aircraft is a 1965 model. However it has alternators instaled. Should the Circuit Breakers be changed out to a diffrent amp rating? I think my aircraft came with generators as the CB panel is labled GEN Front and Rear.
And Last: Anyone out there changed the breakers out to the push pull type, If so what model fit in the space provided.
Its been a long drawn out process for this restoration. However we are almost ready for paint. Special thanks to this site and Don Niesner.
