The LT1 hubs are not keyed, but you can get it cut to use a key.
M6 - keep it in gear with the parking brake on.
A4 - Remove the inspection cover and lock the flexplate with a prybar engaged on the flexplate teeth.
Are you using a torque wrench?
ThunderRacing sells one, already broached, that'll press right on; less than $100. All you'd need then would be a Woodruff key which you may be able to get from them or your local GM parts department. NAPA sells keys, too, but they come in all different sizes, so choosing the right on becomes a problem.
