1989 BUICK ESTATE WAGON3RD ROW REAR SEAT INTERCHANGE? WITH A 79 CHEVY CAPRICE WAGON?

WILL A 1989 BUICK ESTATE WAGON 3RD ROW REAR SEAT...........FIT RIGHT IN A 79 CHEVY CAPRICE CLASSIC WAGON WITHOUT PROBLEMS. OR IS A BUICK 3RD ROW REAR SEAT DIFFERANT THAN A CHEVY CAPRICE CLASSIC WAGON? AND ARE THEY THE SAME SEATS FOR BUICK, CHEVY, OLDSMOBILE, AND PONTIAC ALSO. FOR "B BODY CARS"
THANK'S
SAM

Should be the same from 1977 all the way into the whale-wagons up to 1993 and possibly to 1996 (middle row changed in 1994 and not sure if that changed the way-back as well or not.

Thank's Mike I appreciate this reply. Any information is always welcomed.
