Agree with above Post . 2 Sizes of Control Arm Bushings Being Made today . 1 Size for ORIGINAL Upper Arms , and Another Size for the CHINESE Re-Pop Arms . Moog uses for Example Part # 123 for Original Arms , and Part # 123B for the Chinese Arms . Frank B sent me a bag of those Sleeves to do 6 Vehicles for $100 . I know My local Machine Shops get $100 per Hour . So unless You have access to a lathe , or a Machinist Buddy , Just call Frank B ! Merry Christmas Moparts !
