Like Jeff stated, check the rear end again. You said it had a BU 4:10? BU is a 3:73 posi, BV would be correct for 4:10 posi. Also check to see if the exhaust plate on drivers side rear frame rail is original.Then check out the paint or crayon marking applied on the upper rear seat brace on passenger side. Should be X4 if the trim tag has not been switched. Your body seq # on trim tag seems to match your VIN Build date. X44 and the dual exhaust plate is a good indication that it could be a COPO.
