What about a 3 channel 98 Rear into a 97 3 channel car. I have the opportunity to pick up a 98 3 channel rear with 3.42's complete brake to brake cheap. It would give me better gears and LS1 rear brakes.

Will the swap work with the abs and brake lines, I do not want to get rid of the ABS?

THanks!

 

It is a direct swap. You need the parking brake cables from the 98. Use the hard lines that come on the 98. It will work with your abs.
