Cadillac Repair: calipers on 1991 cadillac coupe deville, cadillac coupe deville, 1991 cadillac coupe deville

Question
My front left caliper froze up and we cannot find a replacement
here in Erie, PA. Apparently it mounts in front of the disk.  Last
Friday the garage ordered  calipers  from auto parts companies, but
none of them were the right one.  My car is a 1991 Caddy coupe
deville. I really need this car because I'm handicapped and it fits my
needs.  I'll appreciate any help you can give me.  The car does have
the ABF system of braking.        
                                                  Thanks,
                                                      Bob  

Answer
I checked with autozone and The reason is there are several types that it could be.

One type is RED POWDER COLOR COATED with 33 or 35 splines. The 35 spline is unavailable. The 33 spline is special order.

The other type is NON COLOR COATED with 27 or 33 splines and both are available.
