89 park ave, what rims fit?

Hi, Im heading to the u pull and want to get some rims for my 89 Parkave. It has 14" on it now. What gm cars should i look for? I dont mind staying with 14 but any size would be a big improvment. Mine had wire hub caps which are long gone.. ugh

That particular year was sort of an odd-ball, but the following list will give you some options to look for.
BUICK ELECTRA 1990
BUICK ELECTRA PARK AVENUE (1989 - 1990)
BUICK ELECTRA PARK AVENUE ULTRA 1990
BUICK ELECTRA T-TYPE (1989 - 1990)
BUICK ELECTRA ULTRA 1989
BUICK RIVIERA (1989 - 1991)
CADILLAC ELDORADO (1989 - 1991)
CADILLAC SEVILLE (1989 - 1991)
CADILLAC SEVILLE STS (1990 - 1991)
