I have a 73 Chrysler that I used 73 up b-body aluminum isolators on. They are not a bolt in but will work. I only replaced the 4 that are under the front of the floorboard right behind the front wheel. I left the rubbers ones at the rear and under the core support, they where fine. You may have to grind the hole in the subframe to make them work or the subframe could have rust issues at the mounting areas. When I took mine out they crumbled to rust.
