Designed for use with stock power steering and alternator brackets. AMC / AMX / JEEP 304, 360 & 401 ENGINES WITH 4 BOLT CRANK PULLEY ---1976+ Generally fits the following models with original 304, 360 & 401 engines installed. Note: 1970 - 1976 are very difficult to figure out the correct because AMC transitioned from 3 bolt crank to 4 bolt during this time frame. Fitament from 1970 - 1976 is not guaranteed and we recommend checking the overall height of the pulleys and number of bolts.
