What exactly are you meaning by "airbag kit"? If you're looking for the lad leveler type for a truck, Brother's used to have one for the '55-'59, and I would think that one for any leaf spring truck could be adapted to fit.
If you're looking for the Passenger car/Mini-truck version that can be dropped to "lay frame", you're not going to find one that will work with the stock type suspension.
