Which motor mount do i need
i understand LS/B20 Rear mount and Driver side mounts same for 92-93… Transmission mount needs to be specific to Cable / auto / hydraulic
What is your question? You will use the 92-93 mounts your car came with. You need to remove the timing cover and replace the drivers side mount bracket with the one from your old motor. The transmission side mount should be unique to 92-93 non gsr mount.
I have a friend who took his car to the shop to have the motor change out to a B20. All they did were just reuse your stock ones.
