if it were me, i would redrill the drivers side 1/2 inch below each hole. then i would fill in the 1/2 space up top with a good weld. grind or flap it all flat and the re drill the holes in their new position, using a bit 1/16 of an inch bigger than the bolts for play. and i would take some off of the top of the mount brackets if they interfered with the block. i cant tell if there is even enough bracket to do that
