[QUOTE="machoheadgames, post: 432533, member: 18789"] I see no real reason why it couldn't be done. If it were me, I'd grab a 4.0 & transmission and make the swap rather than chopping off the mounts to convert them to the 2.5 setup. But understood that could be quite expensive. I don't think you'll have any other issues, everything as it relates to the frame is about the same over all the years. Make sure the skid plate nutserts are in good condition and can be torqued to 50ish with anti-seize without breaking or aren't already broken. That can be a real problematic point on these Jeeps depending on where they live and how they were treated. As for advice, it should be pretty straightforward as a swap. Park it in a spot that's easy to work on. Go through and pull all the wiring harnesses. Engine harness runs down passenger side of engine down to the starter, then to transmission/transfer case and then over to the left frame to go to the fuel tank & pump, so make sure you free that up and pull it up out from under the hood. I would get the old Jeep in the air, move the suspension/axles over to the new frame so that it's a rolling chassis, then just move stuff over one by one. If you choose to cut and weld new motor mount horns, I would probably set the transmission on the skid plate where it needs to go and then place the horns where needed before welding. Make sure you keep the transmission mount oriented in the same set of slots on the skid plate. There is a forward set of slots and a rearward set. I believe the 4.0 uses the rear and the 2.5 uses the front. Reuse whatever it's set in now so that it stays the same later. Good luck, curious to see how it goes. [/QUOTE]
