looking to purchase a moser 12 bolt. found one for sale. But!!!! it's for an ls1 car and i have an lt1 car. would like to use lt1 brakes etc. What would need to be changed to make this rear end work in my car. Joe

 

Backing plates, calipers, rotors, and I think brake lines all need to be switched to LT1 style.

 

Thanks for reply, But wanted to find out if my backing plates brakes & rotors would work. I talked to someone that says everything will work but may need 1/8'' spacers at axle tubes to backing plates. Doe's this sound right? if so, where to get spacers.....joe

 

Everything I listed is what needs to be changed to use LT1 brakes.

You could always leave that stuff and convert to LS1 rear brakes.
