K frame lowering blocks
I did what Phista said to my 65 Dart GT way back in 1983.
It did not change the way the car handled. It was even better on anti-dive during hard braking.
I did have to screw in the torsion bar bolts to relevel the car.
I did have to remount the Z bar for the clutch but the bolt hole was easy to elongate.
The 833 and Hurst shifter did not care.
The brake strut also needed loosening, then retightened.
Had to shim the k member on my 84 Shelby too but that was to correct the SAI miss match from the factory
