well we just did this for my rx-7, and it's an FD. You can tow from the rear tires, just take the drive shaft off and you'll be fine. Easiest way to get at the drive shaft bolts once it's on a two wheel dolly ( and DONT tow the car with the front wheels on ground) is to just either inch the car forward, or backward while it's up on the dolley so you can have the drive shaft to rotate so you can get to each bolt. Also don't forget to remove the brace that's right up under neath it as you can't pull it free without doing that anyways. We drove all the way from here, to maryland, to virgnia, to north carolina and back home with a car being moved that way so you should be alright. Hollar at me if you have any questions about it.
