I replaced my 105a alt with a 145a alt out of a totaled TB with less miles than my truck, for only $45 shipped, moved my engine block ground to a new spot(from the big 3 upgrade), voltage is now much more steady under regular loads, and hold better voltage with my system cranked way WAY up, changed my serpentine and accessory belts, and cleaned the engine bay a little more..sorry no pics this time..maybe when I get later this weekend!!
