You may also look into a Motorcraft 2100 series carb. There is a guy on ebay that sets them up for jeeps with everything you will need. He custom jets them for the area you live in. He is very good about helping out after the sale as well, and includes a cd full of instructions. I have purchases a few of them and install are pretty easy.
Junkyards have them too and they are great, easy carbs to work on.
Only downsides I have come across is that one time a guy on a trail asked me if I was running my CJ on Burger King fry oil. Said my exhaust smelled like fries.
The other downside-- it's still not fuel injection.
