Hi Gchop
My 23 is also a 76 with the large CC. I cant tell you what to do I can only tell you what I did.
First I moved the replaced my gas tank with a 120 gal and moved it forward approx 18' to the deck plate that you can see in my pictures just in front of the live well. I removed the old sub deck the old tank was sitting on and installed a new one the old one was rotten my beat so is yours.
Then I build the live well as you can see in those pictures. Then re did transom, and deck, removed the cap and re did it, repaired CC and on and on and on.
If you go to the picture gallery and look at 23 footers then scroll down to Fellowship there are 30 plus pictures of my rebuild.
Personally I would not put a live well in front of the CC because I like the access to my wiring there and I like to put a fish cooler in front of the CC. Look at the pictures they will answer a bunch of questions.
