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.

Miker,



I am using the spindles to convert to disc brakes so changing them if the car sits too low isn't an option. If I need to change something to bring the car back up some, I can change back to the original springs or possibly re-ream the lower ball joint hole so the spindle sits down flush with the bottom of the ball joint stud which could raise the front up a bit. Then put spacers (washers) on the top of the ball joint threaded end to make the castle nut torque the spindle down correctly. Doing that would also line up the steering stops. The Tbird wheelbase is 102 inches and the Granada is 110. What this conversion with spindles and springs does to the Ackerman is beyond me as is what, if anything, to do about it.

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.
