Yes those are the mounts. And the ls400 1uzfe won't work unless you swap dumps from a sc400. Ls400 are front sump. Sc400 are rear sump. And I just used those swap mounts To mount the engine as low and far back as I could. There is a trick to getting it to fit as well. You have to have the left mount bolted to the motor and the right mount bolted to the stock 240z crossmember. Drop the motor in and line up the left mount in the cross member. Drop the motor more and bolt up the loose right mount. And then fabricate a transmount.
