The 350 tans. might leak tranny fliud w/o a yoke in the tailshaft to stop it? Maybe you could put the driveshaft in and build a saddle for the rear end to keep the rear wheels just off the floor. ( Somethin' more stable than just jack stands). Then you could run it in park and/or drive to run everything.
