Air Bags for 72 K20

[emartin72]

HELP!!!!

I've got a 72 K20 w/ 4" lift and need to install air bags to help support the camper I just bought (also for general purpose hauling of stuff). I've contacted a couple suppliers and they said they had the kits for 73 and newer but nothing for 72. The guys at Air Lift have a kit that they think will fit, but are not positive (it's for a mid 90's F**d).

Is there anybody out there w/ air bags on their 67-72 Chevy/GMC? Any and all help and information would be greatly appreciated.

Thanks,

Erik

PS - Sorry if this is a repeat questions, I tried scrolling thru old messages, but w/ search down that takes up WAY too much time.
