Airsafe and Equalizer

[nedmoto]

I purchased the class V Airsafe receiver hitch with the weight distribution attachment. I attached the plate to the Airsafe and when I went to put on the Equalizer head assembly on Airsafe weight distribution attachment it was so tight I had to hammer it on and now it's immovable on the attachment. I believe it should not be so tight as it actually should move as to adjust the washers. Does anybody have any ideas or am I missing something?

Thanks
