As far as the steering install, not much. Put the A-body pitman arm on.
Did pull the factory A/C out, removed the interior, and pressure washed under the hood. Next step is to trial fit the LS1 and 4L60E. See what kind of clearance issues I may or may not have. Going to hot wire the engine and fire it up while it is in. Unless the engine knocks or smokes, I will continue with the engine swap.
