After reading many threads on fridge conversions, I thought I would give it a try. I got this one given to me, not sure how old but it is metal inside with a non metal door interior. I have taken it down to just the guts, but am not sure whether this insulation is good? I have also included a couple of pics to see if anyone is familiar with this fridge or knows how old this could be? I have ordered a 1500W electric element to go in it. I want to try and use one of those pid units I see alot of. I am hoping to get hot smoking temps. Any suggestions? Thanx a Bunch.
