I'm having trouble getting my u-bolt plate thing (what goes directly on top of the spring pack) onto the ubolts. I got it on fine on one side, a little difficult but no problem really. But now I just can't get them on on the other side. Any special technique or something? Or are they different between a 12b and a 14b? I didn't thik there was a difference and since the other side went on fine I still dont think there is. But still it seems like the plate should be longer?
