8.8 swap

I just saw an episode of "Hotrod Garage" where that had a mid 60's ford truck on a 90's crown vic frame. I assume it was an 8.8, and they installed an Auburn limited slip carrier.

They just removed the cover, pulled the c clips, slid out the axles, pulled the carrier, and ring gear, swapped the ring gear to the limited slip unit.....and bolted it back together.

No adjustments of any kind.

Is that for real?
