I am in the process of putting an LS1 rear into my 95 LT1 car. Now the brakes don't seem to be lining up. Do I need to go and get LT1 axles for my car or is there somebody that knows how much the difference is in length so I can have a spacer made? I have been trying to do a search but I can't get the search engine to work.

 

Either use the LS1 brake calipers (I believe), or switch the backing plates.
