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.

Sorry, Mark, I slipped a cog on that. My very old conversion uses Granda rotors, but with a (I think) different bearing stack to fit the original spindles. And mounts a mustang caliper. I sometimes forget there's more to it than just the rotors when "Granada" comes up. Still, the relative height measurements should let you make a pretty educated guess. A lot of the roads I drive are pretty rough, especially at a bridge or overpasses. I've got a car that's lower, and it bottoms, that's why I didn't change the spindles. Good luck. Let us know how it measures out.
