I think the trans came both synchronized and not. You'll have to pull the top off to be sure.
I also thought that the DT series engines all came with flywheels, and if you wanted the auto an adapter plate was bolted to it to hold the torque converter. If so, All you'd have to do is a quick clean up and maybe a resurfacing and you'll be in business.
