SUBJECT:
STEEL WHEEL REPLACEMENT
MODELS AFFECTED: 1991-1992 BROUGHAMS
1991 and 1992 model steel wheels require use of Metric wheel nuts, 1990 and prior model year steel wheels require the use of English wheel nuts.
If a 1990 and prior model year wheel is assembled to a 1991 or 1992 model, the Metric wheel nuts will not mate properly to the 1990 or prior model
year wheel.
When specifying 1991-1992 steel wheels, use only steel wheels (P/N 9591652) with Metric wheel nuts (P/N 9590477) on 1991-1992 vehicles.
