8.8 Swap

I just purchased an 8.8 out of a 99 explorer. It has a flange on the pinion. Is there a standard yoke to replace this, or will I need to use an adaptor.
Thanks in advance.

Also can anyone point me in the right direction to get some technical data on this swap?

Personally I would just get the flange adapter for your driveshaft or if you are having a new one made for the swap just have them build it that way. IMO the flange is much stronger with its four larger bolts holding it together than the Ujoint/strap style yoke that it has right now.

There are install kits out there for the drive shaft and the shocks, although some of the guys on here fabricate their own.

Thanks for the input. I have another question for the gang. The new rear end will need to be re-geared. I have 35's and currently run 4.10's. Will I notice much difference by going down to 4.56. I'm not sure I want to go all the way down to 4.88. I do a fair bit of driving in the sand, and I'm concerned I may be too low. What are yout thoughts.

This a matter that is debated a lot. Wheelin in mud and sand you need lots of continuous wheel speed to keep it happy. Usually guys that gear down to 4.88 or 5.13 just do most of their sand play in 4hi or in 2nd gear. Honestly there is not much of a difference between 4.56 and 4.88 to really even notice. Especially when you are already going from 4.10. Hell I think it would even make for a nice ride just re-gearing the 8.8 to 4.10. That's one of the ratio's it came in so it shouldn't be hard to find a used r&p for it.
