1971 EV2 Dodge Demon "Sizzler"

Got the 8.75 out of the car. Next week, weather permitting, I'll pull the 8.75 out of the Duster, swap in the 3.91 Sure Grip third member, clean it up, rebuild the rear brakes, and put it in the Demon. Is there any obvious signs that this is an A-Body 8.75, maybe even original, or no?
