You need the motorcraft 2100 with the 1.08 venturi. Rebuild the Carb, buy an adapter plate from the auto parts store (mine was Jasper plate) You will need to fab the linkage from vertical to horizontal. It is not that hard. yo can find several write ups on the net for this conversion.
Once done with the Carb set up right the Jeep will run upside down. My will anyway. I have the 4.2L six.
