Sorry to be a bugger to you about your sale, but the front and rear springs for the SVTF are NOT interchangeable!! They have different sizes, shapes, and most importantly different spring rates. There are several threads here detailing the SVT springs.

With regards to what your dealer guy said, everybody makes mistakes, even Ford service center guys. AND With regards to your assumption of him being right and infallible, EVERYONE should know what happens when you ASSUME things. (ASS - U - ME)
I am an outspoken and enthusiastic Christian. I enjoy evangelizing to people with the help of anointed hip hop & rock. I think there's something truly AWESOME about listening to good music that truly makes you feel good inside.
