Was able to get it back into place right after I posted the question, LOL.
Special thanks to Pedro for his insight and calming response when I asked his opinion of what damage I might have induced when I reversed polarity while installing a new battery. Blew 2 fuses, might have damaged the alternator but it might have also been what lead to the batteries demise (I'm guessing the alternator was good and it was my mistake that damaged it).
Still need to find the second removal key to pull the radio... to check if it was a victim of my mistake or if the fuse on the back is blown.
Had the battery tested... checked out OK.
Got to tell you... pretty upset with myself, negative cable hit the positive battery terminal and grabbed like an arc-welder.
