I haven't picked my fridge up but http://slickdeals.net/f/5467448-Magic-Chef-3-5-cu-ft-Refrigerator-98-Free-Shipping-Home-Depot mentions it can fit a corny.
I bought this deep socket set from Home Depot. It turns out the sockets are metric and the largest one (19mm) won't fit either post. The socket fits slightly better on the out post but its still too small.
It it possible that both posts use 7/8"?
