Leaf Spring Bushing Sizes

Steve,
I wish I would have ran through my issues back in Feb. I have the bushings/bolts that you need(ed). They were, however, listed for a '69 Dart \6 as 'leaf spring bolt' and to be used in the shackle (??) at RA. They looked right to me without having dimensions listed so I ordered them. Two months later I have gotten the old bushings out and those new suckers better expand a full 1/8" by application of some Mopar fairy fart dust or they ain't gonna hunt! I had no idea I was opening my own version of pandora's cardboard box that is this "front eye bushing issue" when were left on my doorstep. My old ones are 1.5" OD x 2.5" W x 1/2" ID (bolt diameter) - Is there a part number for that? Why is it so hard to get these listed right? Were there that many changes made through the years/engines?
