There is the back part of this bolt has to move quarter inch while you are hammering! And you will see that alternator start getting loose. And then jiggle the alternator and see how loose it become. If it is not that loose hammer back again! Once it is loose remove regardless of order bottom or top bolt and put the alternator to the bottom of the engine tray!

Yes, thanks, I read that, and it reminded me of the posts in this thread from the user who I think also points to the same bolt in the back as the solution to the removal problem. I look forward to seeing what happens....

Here is a great read regarding why the alternator doesn't come out after removing the bolts.

Here is a pic of the "sliding nut" that "locks" the alternator in place and needs to be tapped out...

What you'll need to do is get some wd40 or something to lube up where the bolts slide into on top and bottom of the alternator, let it sit and literally use a crowbar and yank it out. Depending on how old the car is, it'll be budged in there. Mind took an actual crowbar to get it out, you really gotta pull and push until either the top or bottom slides out. Everything after is simple
thanks for the tips. did you follow op's method of getting to it - remove air box and radiator fan?

thanks again.
Yes the fan will be a bit of a pain to get out, I broke a clip on the right side but just take your time and apply pressure lifting up.
