8.8 swap please help

After my recent issues I think I am going to do the 8.8 swap so if I have issues there are people who know what the hell is going on. I do have a couple of questions.

I found an 8.8 out of a 96 explorer with 4.10 gearing for 200 bucks. In the front of my yj I have an ARB air locker will these work together?

Do I need to relocate my shock mounts? or anything else for that matter?

everyone talks about getting "brackets" after market instead of using the ones off the d35 are these the brackets that sit under the springs and hold the u bolts over the springs?

If anyone can point me to a thread where someone did this in a YJ and left it SUA I would be very grateful because I can't find a single thread anywhere without it being in a tj or going SOA.

This all depends on the gear ratio thats in your front axle, the locker is irrelevant.

then you probably have 3.07, but check for a tag on your diff cover to make sure

If I have the 3.07 gearing I have to re-gear then?

YJ's came stock with 4 ratios;3.07, 3.55, 3.73 and 4.10(4-cyl). none of them came stock with an ARB. The only way to be sure of the ratio was not changed is to count the teeth on the ring and pinion. 41 ring teeth divided by 10 pinion teeth = 4.10

Also I would not get an 8.8 without Limited Slip unless you plan on locking it.

Its a fairly easy swap.. Rough stuff specialties has the bracket kit you will need, has to be welded of course. Also weld the axle tubes to the diff housing.. If you going to get a rear locker get a full case locker such as another arb or detriot.. as the stock carrier in the ford 8.8 is rather weak for running a drop in locker such as a lock right, etc.

An 8.8 should handle anything you want to do to it up to 35's, then start worrying if you choose to cut corners. Needless to say, if you lock your rear axle and want it to drive well on road you should get a selectable locker and spend the $1000. For me a LSD was enough.
