so just to prove it:
16. Will a 3 channel rear end work in my 4 channel car?

Yes, you can make it work, if you put the axles from your four channel car into the 3 channel rear end and install the sensors into the backing plate. To put a 4 series into a 3 series would be more difficult, because it would require you to drill in the top of the rear housing for the sensor, and add a reluctor ring to the carrier as well.

anyway, does anyone have an exact write up or link to a write up on how to make a 3 channel work on a 4 channel car? my 10 bolt bit the dust and all i can find is a 3 channel rear to swap into. just curious how in depth this is, because im on limited time and funds. just wanna make sure it is with in my skill/tool range. thanks

not much of a write-up required
both rearends:pull covers and remove paddle(torsen) and/or center pin(auburn)(you didn't state what year the donor rearend is),remove c-clips(remove 4 channel sensors if needed to facilitate c-clip(s) removal),pullout axles,unbolt and swap backing plates(instead of making holes in the 3 channel backing plates) and swap axles.
be opportune time to check axle bearings(in housing) and bearing surfaces on axles.
98s' would have auburn posi,99-02 would have torsen.

I wonder why you can switch from a 3 channel to a 4 without issues but not the other way around? Wouldn't you just lose your ABS and TCS funtions?

Sorry about the 4 channel to 3 channel though, I don't have any knowledge on that.

You could use a 4-ch in a 3-ch car by disabling the ABS/TCS. The hole needed for the sensor on the pumpkin in a 3-ch is not machined out on a 4-ch and you won't have the sensor wheel either.
