Wildman Posted October 10, 2008 Share Posted October 10, 2008 Think of it this way-- The difference between night and day :roll: Every thing between the fuel pump, and the hood latch needs to be changed out. Link to comment Share on other sites More sharing options...
JeepcoMJ Posted October 10, 2008 Share Posted October 10, 2008 it's all bolt-in except for the front end/radiator supports, but EVERYTHING needs to be changed. one spot on the firewall may need to be hammered back too. Link to comment Share on other sites More sharing options...
mvusse Posted October 10, 2008 Share Posted October 10, 2008 Everything means EVERYTHING, including transmission and if 4wd transfer case. Possibly drive shaft(s) as well. Easiest would be to find a donor Cherokee, and move everything over except the rear drive shaft. If you have a 2wd, this might be a good time to convert to 4wd at the same time.

Eagle Posted October 10, 2008 Share Posted October 10, 2008 It will also require a complete engine wiring harness, and it may involve some alterations to the chassis harness, as well. For example, the V6 has a mechanical fuel pump. You'll have to get power to the tank for the electric fuel pump. Oh, yeah -- you'll need a gas tank and fuel pump.

mvusse Posted October 10, 2008 Share Posted October 10, 2008 Even the gas tank is different? You'll need the sender unit as the one for the V6 doesn't have a way to mount an in-tank fuel pump to it. Link to comment Share on other sites More sharing options...
