I was looking at Holley Carbs for a while but never found an exact part #. Summit has a great selection of smaller carbs, if you contact them they should have a suitable suggestion. I changed my mind and got a Motorcraft 2100 after reading about them here. I still need the adapter plate (Lots of posts here with the part #, I forgot it). After that I just need a plenum to my Wrangler filter box, then my total cost should be less than 100$. A new Holley may cost more but anything seems better than the Carter.
