Bushings on the A arm suspension pieces are difficult to remove/install. I think you can get the tool that helps as a loaner at the parts house. I also would add front disc brakes- you can get them from 1973 and up older Mopars A bodies that work well- and add the safer dual reservoir master cylinder.
Yes! Agreed! I was told that the ideal setup might be drums all around if I can’t find a disc set, and to go with the 1968 barracuda reservoir and brake lines
