4.0 motor swap
Ok, question 2, do I need to slide trans back to pull the motor. Note: I’m pulling this outside so the less I have to do the better. No lift, rigging off an oak tree😂 I know I have support trans front.

Sure don't. Radiator removed. air cleaner assembly removed. Battery removed.
Put power steering pump where air cleaner was and AC compressor where battery was.

The hardest part is getting the top inverse torx bolts that hold the trans to the engine. Those two bolts took forever both times I pulled a 4.0 motor without the trans. You will need several extensions and a wobble head to get them. Google it to prepare yourself. I found it helped to drop the trans mount and tilt the trans down to get some space and angle to get those bolts out. Not fun at all. One gotcha I had on reassembly was the power steering reservoir. Air got into the system when I had the reservoir set aside. Ran great for a few minutes and then sounded like wailing monkees. Pulled the cap and re-bled the system to fix it.

I have a 4.5” lift on it so the trans crossmember is spaced 2” hopefully it’ll give me enough room but thanks for the tip. I’m mentally prepared for those😂😂😂
