I know in my Redline kit it had two different install locations depending on what kind of hood you had, maybe you used the wrong measurements?
Nope, used the measurements for the 79-93 hood. I'm convinced that the lower mount points on the driver side was probably 1/8th" or more off. probably enough to compress the shock too hard, and it wouldn't compress anymore and the result was a bind. Bottom line...my fault.
