1994 caprice classic what leather seats fit for them does anyone know please tell make and year thankx

I would say Cadillac seats, from 1977 through 1996 on RWD DeVille/Fleetwood models (C & D body) for the front seats, or Caddy D-body 1991-1996 Fleetwood for all of the seats.

Its really the existing frames that you should look at, i have bonneville seats in my 89. just rebolt your factory seat frames to the bottom of the new seats and when you replace them they should line up just fine. make sure you measure them though.
