Default Ls1 to Lt1 Rear Brake Swap (Traction Control) What's Needed?

Long story short I ended up with some non f body specific billet specialties. I know these will work with lt1 brakes with a little grinding(came off lt1 car). Ive grinded my ls1 brakes A LOT and they still don't clear. Im afraid to grind more.

What will I need to swap lt1 brakes on my traction control ls1 rear? I know I will need calipers, brackets, rotors and backing plates. Will the rotors or backing plates need to be traction control specific to fit? Thanks

I dont think the older Calipers will work with the 98-up Master Cyl..I read it somewhere and there is a difference in the brake line pressure when you are not applying brakes..I'll look for it.

Thats interesting. The car they came off of was a 00 with a 12 bolt with lt1 rear brakes. It has abs delete and a proportioning valve, not sure if that made a difference.
Let me know if you can find the info
