Strut rod bushing on a 66 A body

I bought Moog K7040 bushing kit as listed for my barracuda from rock auto. The Kit contained 4 bushings, 4 large washers and two small pins. The washers are quite a bit larger than the ones on the car, and I don't think the rear one will fit. I also don't see anywhere the pins would apply. Anyone used the Moog on a 66? I have read every post on here regarding strut rod bushings, and I'm more confused than ever. Also, is it necessary to remove the lower control arm to change the bushings? Thanks
