newbie needs help on body vs engine swap

My 95 tub has rusted in the normal places (driver/passenger floor, passenger rocker panel/both front fender) so I purchased another 95 that has good tub but a blown engine/ 5 speed lacking 5th gear. I had planned on swapping my engine/tranny/transfer case but then I thought it might be simpler to just swap the tub w/front fenders. What is the general census as to which route is simpler. It's getting cold here in NY and this has to be done outside or quickly in my garage. By the way Happy New Year!

If the engines are the same, i'd think that swapping drivetrains would be easier.

Drivetrain for sure...if your tub is rusty those eleven body mount bolts will be a real pain. How's the frame in the "new" '95?

An engine and tranny swap is much easier than a body swap.
No rusted body mount bolts to mess with.

Yes the 4 cyc.engine/5 speed tranny/transfer case are the same. Both frames are in good condition but i don't know much about the "new" YJ such as brakes/suspension. I thought I'd try the body mounts and if they weren't completely rusted closed. What I don't know is whether there is a junction block or harness clip somewhere that would make it easy to disconnect the electrical systems where they enter the tub. I don't want to start disconnecting tons of wires/individual harnesses.

I made a thread years ago about removing the tub. Go find it and you will see all the ins and outs of it.
IF the body mount bolts are OK, AND you know that everything else on your rig is better than the "new" one, then just swap tubs.
It doesn't take a long time to switch them, and will save the cost of coolant etc too.

If the tub is rusty, be sure to check the frame for rusty spots around the spring mounts and stuff like that. I would hate to see you transfer a different tub to your frame only to have problems down the road. It would seem more likely that the jeep with the non-rusted tub would also have the better frame of the two.

Here is the way I would try this. Remove your tub check out the frame completely. Then decide if that is the way to go. This way if you decide to do the engine transfer it would be easier to do. Also if you are going to do a tub swap I would get new body mounts (I would go ahead for a 1 inch lift body too) for it. But hey this is my way that I would go your choice.

Taking the body off make engine/drivetrain 100 times easier. Plus you can inspect the frame and grind off any rust and paint POR15. Why not do some rust preventation while you are at it?

Pull the motor and trans. You can do this swap in a day. If you pull the tub tou will have at least 3 days into the job. Save the rest of the drivetrain if the new one has issues you just bolt on the ones you know.
I have done both and so I do know.

Huh? 3 Days to swap tubs?
I have done both, in various forms from a direct engine swap to a frame of restoration, to a Chevy engine swap, and so on.
If you can't swap tubs in a day, you have issues IMHO.

If you are talking apples and apples. Both 4cyl, both bone stock. Both have titles that you can use. Both have good frames.

Swap the motor and tranny, would be my suggestion.

Yes they are apples and apples. Both the same year, same motor/transmission/transfer case/axle ratio/color. Only difference is that I have a hard top w/full doors & soft top w/half doors. The "new"YJ has a good soft top w/half doors/ sliders. I also have a wench and chrome f/r bumper/bumperetts. I think taking off my tub and checking the full frame is a good idea and if I decide to swap the engine/tranny/transfer case I'll have access to everything. Ether way, I'll do some rust prevention.
