Lots.
New leaf springs(mid eye to lower it by 1 inch but raised it by 20mm),
new wheel cylinders and adjust brakes,
fix horn that kept going off,
fitted window regulator rollers,
holley accelerator diaphram.
Drives awesome now and doesn't wallow around corners or under acceleration/deceleration and brakes have stopped 'grabbing' so now A HAPPY CHAPPY, can't wait for the next cruize.
Time to start saving for next .........whatever I can find
