To anyone who has done this job - is this better tackled from the top side or underneath? Or both?
Looks like if I remove the alternator it can be "reached" from above.

you got it, pull the Alt and everything is right there. Maybe clear the plug wires and the #2 plug, but that probably isn't needed

Thanx.
Someone told me to wipe a hefty wad of grease onto the pushrod so it will stay in place while getting the pump and gasket in place. Sound about right?

Yep.
Piece of cake with the alternator removed.

Excellent - thanks.
Previous owner installed a Carter electric pump which is making 9 psi at the carbs inlet. A little high, but I don't think its causing problems. Fuel bowl levels are perfect when sitting still. That said, the pump is loud like a compressor and it has to go.
Oddly enough, included with the extra goodies when I bought the car were two mechanical pumps - a mopar pump which doesn't look "correct" and a Holley high volume pump.
I got a high performance Carter pump from Roseville Moparts, which they say is correct.
