I haven't dropped out the bottom w/o a lift. However Hitman just did and said it was pretty easy to roll, you leave the tires on and the whole thing rolls nice.

On the 88, all your engine/trans mounts are on the bottom except the TA mount on the passenger side. That might be a pain point for you. Because that holds the engine/trans on that side. The only other mount is a dogbone from subframe to the bottom of the trans. It might be enough though. You have a lower front and rear trans mount on the driver side..then that one doggie on the passenger side. it might not fight. On that TA mount.. lift a little..pull the one main bolt and it should all slide rignt down.
