Here is my 8.8, it is offset some but not a big deal. A lot of people run them and so far I haven't heard anyone who has had problems with it being off the center line by a few inches. And I don't think that you need to angle the motor/trans to make it work.
Thanks for the photos, they will be really useful when talking to my builder. Does the fact that you have a 51 alter or change your thoughts that this should work given your truck demimsions are not the same as mine? I do however, no that Ben and otheres on here that have 48-50 have used this same rear end with great success. I am really hoping that we can work this out, I really want this posi rear end in my truck.
We've got 10,000 miles on our's - no issues.
The 8.8 rear axle swap is the easy one. Wait till he get's to the front
axle replacement. Now that one took some effort & involved cutting into the frame & some pretty exact measurements. The front suspension replacement is not for the faint of heart.
Having Posi traction is nice. I've got one car that's not posi - my wife's afraid to pull it up our steep driveway - doesn't like the rolling backward thing.

Derek, the link in my post gives good info on this. Pinion offset is no different that pinion angle and since the engine and the rear pinion shaft should be installed parallel with the frame you don't even have to set "angles" like you do when setting pinion angle. Hope this makes sense. Here is a diagram the one on the left (A) is wrong, on the right (B) correct. This shows the engine offset but would be the same with pinion offset.
I totally agree and was waiting for someone else to post it...lol. Two points that you can either accept or choose not to...
1) MANY people are running the explorer rear and have posted here telling you IT WORKS FINE. These people have actual experience and are good folks so I know they are telling you honest info.
2) any "builder" that thinks a driveshaft will magically "know" that it's inserted into a chevy versus ford tranny is on something. RUN!!!! A chevy tailshaft or a ford tailshaft for this purpose/situation make NO difference as far as lining up or slightly off compared to the rear end.
Not trying to be short or rude but some of the "builder comments" are so out there I feel like you are asking for trouble dealing with him. Just trying to help. I hope you take no offense.
+1... Since he is clearly clueless on this aspect of the "build", I'd grill him closely on what angle he is setting the perches/pinion at. Make sure he is setting the axle so the perches are equal distances from the end flanges, not the pinion. I wouldn't trust him, to be honest.

After talking to my guy and sharing with him what you guys have shared with me, we are back on track and believe we can make the rear end work. AS many of you have said, I couldn't understand if so many of you have done this, then it was possible. Will provide more infer as we prepare to install motor and transmission early next week. Thanks to all!!!!!
So, you had to convince your "builder" that it could be done? Are you paying this person? Are you doing a complete truck build or just swapping the rear? I hope this works out for you but I would of run away already.
