yup on my duster the springs had to be moved in 3" on both sides in order to get the clearance.
but they for sure make for a sweet look and give more tire to hook out back.
I personally love the look of the 14" front and 15" out back....but I think your buggy would probably look best with a matched set all around.
I know the feeling of little things doing alot for mood. yesterday My new carb arrived and it made me a feel a bit better lol. not to mention summit hooked me up with 2 free tickets to the US131 drag way ,so that was a plus lol.
glad things are coming together for you on the buggy! she sure is a beaut!
