Brakes are the only difference, abs channels are different and brakes them selves are different

Did you have to swap the axles for the LT1 brakes to fit, or was it becuase of the abs? I'll be doing this swap shortly but I am going to delete the abs on my car anyway. Sounds like I might need to track down an extra pair of axles.

I replaced the Auburn cone in my 95 with a Torsen Zexel out of a 2000. No axle swap or anything. It was a direct replacement. The only thing that had me wondering was the reluctor ring was wider with the Auburn but my ABS worked exactly as before after the swap.
