Air shocks

I ran air shocks on my 70 440-6 car, they were on it when I bought it from my friend and OO at about 35K, and were on it when I sold it, although they had been replaced. I sold the car with 150K on the chassis, and nothing had ever been damaged. I did NOT use them to jack the thing up much, mostly for heavy loads in the trunk.

Since a B is a lot heavier than an A, it stands to reason that the stress might be more

The car, around 1974 or so, n' ya, don't I wish I could afford one now!!!
