Yep, with a few washers on the driver's side for a spacer on one bolt, and mod the passenger side mount as shown in #3 above. Or, you could just use the passenger side bracket as is if having only two mounting bolts is OK with you.
Washers on OEM 64-66 driver's side rear bracket bolt:
If you didn't want to mod them Ebay has a set from iirc Norms speed shop for $375 +15 ship & mancini has a set for $150 but may be on back order. I have no exp with either set.
