Lots of guys suggested the ride height being to high and its hard to tell from your picture but it very well could be an issue. I changed out a set of super stock springs years ago on my 9 second 74 Duster as the other set had LOTS of runs on them. Well the car sat a little higher and that car was terrible to drive. I removed them that week and took them to a spring shop and had them de-arched some and the car worked great. If possible post some better side, front and rear pictures and the guys on this site will get you straightened out.
