modifying A arms for airbags

Ive got a 61 chevy wagon on airbags and want to get it lower. Ive got 2 ideas on how to do this. Please let me know what you think.

1) 'Step' the ball joints up. This will raise the spindle, and when the bags are deflated the wheels will be that much higher which equals being lower. Ride quality will be the same because the air in the bags is the same and has not been changed.

2) Leave the ball joints alone. Plate the bottom of the A arm and then cut out the original spring pocket and bolt the airbag right to the plate. The same amount of air will allow the car to have the same ride quality, but it will ride much lower.

I understand that either option will take more air in the bags than it takes now to get to the height it is at now, but I want both the parked height and the ride height to be lower.

Again, anyone thats got any ideas = = please put it here before I start cuttin !!

You need to buy dropped spindles. Rasing the ball joint will work in theory, but you'll have to figure out how to raise the upper ball joint and equal amount without affecting suspension geometry. You have to keep the angle of the upper arm the same if you keep the lower arm the same as stock. Angling both up an equal amount would work, but would affect how the car steered and rode later. More than an inch or two of drop changes steering geometry to much.

Farna is correct, the correct way to do it would be to install a set of dropped spindles.......modifying the ball joints and getting the air bag out of its designed operating parameters is not the way to go. I know that with our kit on my 63 the highest point of the front fender was only 19.5" off the ground with factory spindles. That was using a 25" tall tire.
