Air bags on a 68

[67chevemall]

Thanks for the info guys!

I have cut coils in there now and I like the height it is at. The rear coils are uneven now from sitting so long. Instead of putting new coils in there I decided to go with the Bags.

The front should have spindles as the outside edges of the tires are worn away.
I'll get them when I get new tires and rims. (The last step before paint.)

I spent $50 on the rear kit just incase but I guess I can return it because I have coils back there.

What do I need as far as Bolts go??
Do they need to be bolted in there or do they just sit like coils do??

Thanks for the help! I need to know what I'm doing before I dive in there.
