These will fit the GM intermediates rear using 14" or larger disc rims and most drum rims.   This uses 1979-1985 Cadillac Eldorado calipers and 1982-87 Camaro/Firebird rear rotors.   These brackets have special formed centers of the same gauge as drum backing plates allowing for the use of bolt in axles and C-clip eliminators.  Also included are welded hose retainers.
