Do you need the heater itself?
It's NLA but I replaced one of my 1964 Frigidaire bottom-freezer fridge with a model that apparently still is (sorry I don't have the part number, I got this part from a lot and there was no part number on it). The heater isn't as long as the original and I needed to bend it to fit around the evap and also skip some rows but it works... As I write this, I just heard the fridge restarting from the defrost period. My former heater still worked but it was shorted to the chassis (which isn't grounded) and I got electric shocks from touching the fridge's chrome trim and my range's chrome trim at the same time!
