Do yourself a favor in the future, buy your stuff at the local parts store. LMC blows for most things and even more for something you can buy at any parts store in America.

Your suspension is 73-87. You need to always buy parts for 73-87. 73-87 do not use greasable bushings on the control arms, 72 and earlier did. The parts are not interchangeable. The only bushings that will fit your control arms are 73-87 spec.
