Man, RipperXX, you sure got your hands full! But you're doing terrific and with a very good attitude. Many of these trucks get sold because the previous owner just stopped maintaining them...yours' is a good example.

Regarding the temp gauge - that's where mine reads at operating temperature, after a reaching almost half way before the thermostat opens. It would be a good idea to look into the system, but at present, I doubt you're getting false readings.

On the emergency brake - my experience was that the hand brake worked a whole lot better when the rear brakes were rebuilt. RockAuto has the entire spectrum of parts needed for these truckls, and I completely rebuilt mine for about $80.00.

Removing the rear drums requires two 10 MM bolts, don't try to beat the drums to death getting them off. A quick inspection is a good idea, and you'll know what's going on back there.

Great photos, thanks for keeping us abreast of your progress, and I send all the encouragement I can !
