i recently did mine. its not as bad as some say, i took off my wheel well, but i dont think i needed to at all.
the only bolt i recall accessing through there was on the alternator bottom, which can be done from the top.
patience when it comes to feeling things out when putting the bolts back in.
also i didn't use that metal bracket to clamp the valve cover down? seemed impossible to install and take the pump off.
or i would have to of taken alot more off to install the clamp, just eased the pump off.
edit: ahh yes, my post is on patricks thread.. those terrible terrible pulley bolts, i bout near broke a screwdriver trying to remove them.
i got a 90 degree dewalt adapter or somethin of the sort and tried to use my drill as an impact.. that was the biggest challenge.
