Well at least Dexter actually runs now. I finished putting the old, tired alternator back on as well as running all new power steering hoses. Of course, I failed to take into account the fluid level change between running and not running so a reasonable amount of ATF belched from the power steering fluid reservoir after running for a while. Nevertheless, after what can only be described as a very shaky liftoff, Dexter lives once again. He has acquired two new fuel-related issues, however: 1) the electric fuel pump now buzzes — probably needs to be replaced, 2) the seal between the top of the sender unit and the fuel tank is leaking.
(Update 08-Jun-2008: Leaky fuel tank sender seal issue resolved and alternator seems happier than it used to be. Car goes. Life good.)
