Airbags with a straight axle

[misfits1981]

Morning all - I tried doing a search but couldn't find a thread for my question(s). I have a 1957 3100 that's lowered with lowering springs front and rear but I still want to go lower. My dad and I found a guy at the Pomona Swap Meet that will bag the truck, front and rear, with the stock straight axle on the front.

My questions are - has anyone done this? If you have, what's your experience? I know IFS is the way to go but my dad is reluctant to cut the truck up since the sentimental value is higher than the cost of upgrading to IFS. Any pics or input is appreciated. Thanks!
