LT1 and LS1 backing plates the same?
I just put my stock rear, DS, torque arm back in the car this week while I'm deciding what to do with my 12 bolt. Fortunately I bought an extra set of LS1 backing plates a couple months ago.
See if you can get some from a bone yard. Most have the complete rear brakes, backing plates and all for $150-$200.
Unless I'm misunderstanding you, that's not going to help you. The LT1/LS1 axle housings are the same AFAIK. Only difference is the brakes. See if you can scrounge up some LS1 backing plates.
