Paul it rode like a freaking dump truck! Part of why they are coming off and they lifted the car almost 4". Thye have 5 leafs in them vs the Firebird 4 leafs also.
They flat worked though. On the 78 when racing NMCA I tried just the Herb Adams relocating front spring eye up 3/4" for increased antisquat, then that plus a slapper bar before I ordered these from Greg.
I did have the replacement springs made with the second leaf all the way to the spring eye.
