Quote: They used slider mounts. I have a pair of those mounts in my garage waiting to go back on the hot rod if it doesn't sell with the big brakes.
Rockauto.com lists 11.75" rotors for an 1981 Grand Fury. Most of them were the 10.8" rotors but some police package cars had the big ones.
Once again, never say never with Chrysler.
1980-1981 Gran Fury is an R-body. It became an M-body in 1982. QED R-body = 11.75 rotors.
Maybe your Diplomat cop car was really a St. Regis? But, its an easy 2 hour upgrade. Police depts. scrapping R-bodies and buying M-bodies... doesn't seem like a leap to me. And then those M-bodies becoming taxis.... I saw them in service at college from 98-2001.
