@foone that looks a lot like the 25-year-old kenmore I have (torn down twice - the first one was an actually burned-through heating element (in that square-tube on the right), the second was three of the wheels no longer turned - hair burned in to a carbon layer on the bearing shafts.) For both of them, getting it to the stage you're at was the hard part; the parts are turned out to be pretty easy to get (the most recent repair was this year.)
