Rear end swap and gearing

I am looking to rear end swap to the Ford 8.8. Something in my differential gave way last time I pulled my small boat a short distance and at low speed.. I have a 95 yj with 5 speed manual, geared 3.07, 4.0L, 4x4, 33" buckshot tires. It is strictly for offroad and hauling boats and farm equipment short muddy distances and rarely leaves our farm. I am looking for general and installation advice.

I think I found the rear end I need off of a 2000 explorer that is geared 3.73. I have been trying to figure out what ratio I should use to have enough power and grip to get out of muddy spots and still have it run well at 65 or 70 mph. There are a few options I am banging around and I'm trying to figure out what is the best bang for my buck and time efficient. So far I am leaning towards re-gearing to 4.10 but I have been warned that it may be too much for the engine or transmission, please advise.

option 1
keep everything in the used rear end, 3.73, get the welds needed, attach to jeep, limp to someone that can regear the front end to 3.73, hopefully drive home happy with 4x4 capability. I think this is the cheapest route that is still a good upgraade, please advise.

option2
take the used rear end to get re-geared first, re gear to 4.10 or 4.88 and maybe add a locker of some sort, get the brackets welded and bring it home and install, then drive the jeep in 2 wheel back to the shop to gear the front end same as rear.

option3
drop the front end and bring both at the same time to re-gear and then install each back at home.

option4
get another jeep axle thats 3.07 and wait for it to break again, and have no 5th gear or great mud capability. <i'm not leaning towards this one but there may be an easier way than my above options that I'm unaware of or haven't given enough consideration to.

I have a mechanic that comes by and helps me with alot of stuff but he told me this might be past his level expertise (he works in a transmission shop) and I know he's worried about doing it because it is modification stuff that he hast done before. I just want to get the jeep back on the road ASAP and mitigate future problems with it. It's run great up until this mishap.

I really appreciate any and all advice on this project. Links to how to's and the correct parts would be amazing. I spoke with one of the guys at jeepaddons last week and he was really helpful so I think I'm gonna order parts through them if possible. I'm going to update my jeep profile and pics tonight!

How about option 5:
Find a front axle out of a 4 cyl. That has 4.10 gears stock, and regear the 8.8 to match. Add locker if desired.

Last time I looked, you could pick up a 2.5L front axle for about $300 MAX, complete with brakes and everything.

also iirc, if you can find one, it was either the fx4 or the "splash" model of ranger that had 4.10 gear ration in the rear end....might get lucky and find one at your local dealer, they had the 8.8 in them as well

Rangers have a 28 spline weaker 8.8. People swap out of an Explorer because they are 31 splines and a much stronger axle, plus the 95 and up had rear discs for easy maintenance. All 8.8's are not created equal.

8.8 also comes with 4.11's so find one of them and save on the rear gear.
