Rear Spring Solid Isolator Conversion Kits
Early models were equipped with rubber Rear Spring Isolators, which are prone to collapse with age. Later cars were built with solid metal Isolators not subject to collapse. It is a relatively easy job to convert those cars still fitted with rubber Isolators to the later solid type.
Applicable chassis ranges (cars not originally fitted with solid Isolators):
Countries other than USA: chassis numbers 01001-16213.
USA model cars: chassis numbers 01001-15555.
