1992 Other Cadillac Models Brake Rotors

I have a 1992 Cadillac Fleetwood Brougham, the front brake rotors are totally shot and I dont have the money to buy new ones right now.
But i also own a 1988 Fleetwood Brougham, same body style, both RWD, both 5.0L V8. The front rotors on the 88 are pretty much brand new, I was wondering if they would fit / work on the 92.
I know the only differnce is the ABS but im not sure if either car has it. Or what the differnce is in the rotors.
I plan on buying new parts when I have the money, but till then I need a car to drive, and you cant drive it the way it is.
