108 wb versus 111 wb leaf springs

Well guys, I was mistaken on the wheelbase of the Duster, but I still contest that the leaf springs I used from the 340 Duster were longer than the original ones from my 66 Cuda. Of course crackedback could be right in the fact that the arch was different, or the fact that they were HD was making them appear different, but I got them from my now deceased buddy "Mopar Joe", and when I got them he stated they were a little longer than the early A's and I would have trouble with that, and I did!!!I'm gonna recant my original post, but stick with my experience!!! Sorry to add to the confusion around here, i'll shut up now!!! Geof
