FWIW, I used the Moroso aluminum bushings decades ago in my second gen 73 T/A, Everything bolted up and never had to worry about the subframe shifting as the rubber compressed. I also had a 76 T/A with OEM bushings that was like a rubber band when you jacked it up.
If I was ever to own another subframe car it would have something besides the OEM bushings.
