8.8 swap

Does anyone know how much the 8.8 pinion offset within the pig is? In other words what's the offset after equalizing the axles?

I've seen a measurement of 3 7/8" difference from pinion center to the axle flanges. This would work out to about 2" offset from the diff center. That is the number given for pinion offset in this reference:

If my math is right taking off 3" from the long driver side will give a new pinion offset of 1/2" to the passenger side, indicating this is the offset of the 8.8 within the pig. Does that make any sense? :scratch:

The math:
59 1/2 (8.8 disc to disc) divide by 2 = 29 3/4 to center.
29 3/4 less offset = 27 3/4 short side disc to pinion center.
59 1/2 less 3 = 56 1/2 shortened diff disc to disc.
divide by 2 = 28 1/4 to diff center
this is 1/2" longer than the short side disc to pinion center.

My reading says the 8 3/4 is either 1 3/4" or 1 3/8" offset to the passenger side. If my math is right the shortened and centered 8.8 has its pinion centered about an inch to the driver side of the 8 3/4.

Edit: The 8 3/4 pinion offset is about 1 1/2" to pass side. The shortened 8.8 offset is 1/2" to pass side. This places its pinion about 1" closer to the driver side.

My purpose is to see if it works to cut an 8.8 down to 50 1/2" disc to disc for my Demon. Dutchman says they need to cut a minimum of 3.5" when shortening 8.8 axles. If the above is right the short side can be cut down 4" and the long side by 2" plus 3" (total 5") and wind up right where an 8 3/4 has its center.

It's late... I could be way off :drunken:
