Ready to install tranny but???

[scooby3242]

OK Im swapping my saginaw 3 speed to a th350. Im ready to put the th350 in but having never done this before I have a few questions. Before I install the flexplate is there a spacer I need to remove? And before I put the torque converter on the tranny should I put a quart of tranny fluid into the converter. After getting the tranny bolted to the block and checking the spacing from the torque converter to the flexplate, how does the flexplate bolt to the torque coverter. Do the nuts go on the flexplate side or the torque converter side and do I use washers. Thanks
