Here is a photo of my original stock 57 Tbird spring standing next to the CC850 Aerostar spring from Rockauto. The standing free height difference is substantial. Is this what others have found? I thought I had cut the original springs but looking them over I didn't when I replaced them 7(?) years ago. Any comments will help. Don't want to make a mistake putting this on with the Granada spindles.

Mark, run a search under Aerostar for my June or July post. The spring heights, fender height, tires etc. are all there. You can add in the spindle change, mine are stock. Should get you within a 1/4" or so. I've got the alum heads, manifold, headers, timing cover, water pump, and probably 20# more on the front for the a/c. Once you drive those springs, I'll bet you change the spindles before you change the springs, if you're too low.
