tools need to remove driveshaft 1988-2003 Dakota/Ram 1500 ?

Well I need to get a driveshaft (no 2 piece driveshafts) that was used for an A500/A518 overdrive trans. That might be better info.
Ok, bone yard will probably call that trans a "42RE" and should have a saddle type. Could be either 7/16" or 5/16".
