I have an old (think Honeymooners) GE fridge as my kegerator with a tiny built in freezer, like the dorm fridge's. If I can remove the freezer portion, I can fit 3 corny's in there. I believe the freezer is made by just adding more coolant loops to the freezer section. I dont want to cut and solder because I'll lose all my refrigerant. Any suggestions?
