Does anyone know how I can convert a 3 channel LT1 rearend to a 4 channel rearend?

 

more work than it's worth, unless you are adding traction control (which is the reason for 4 channel).

If you are asking about just installing a 3 channel rear on a 4 channel car, all you need to do is add reluctor rings to each axle (or install 4ch axles) and mount the 4ch backing plates (they have holes for the sensors).

 

Off the top of my head, I would say you would need to change axles, add the sensors at each axle and the accompanying wiring.

 

The deal with my car is it was wrecked before I had it and it needed a new rearend. The pervious owner put a rearend out of an LT1 car in it and now my ABS on the rear wheels and TCS don't work. I'm going to pick up the damaged rearend from the car tonight so what will I need to switch to the LT1 rear to make everything work?

 

Edit: what is damaged on the original rear?

 

Not that I know of, I'll know more when I go pick it up.

 

I've got the rearend now and all that was damaged was the panhard mount was bent, everything else is fine. What all do I need to take off to convert my rear to 4 channel?
