front sway bar for a 69-72 4x4 w/leaf springs

[Terrysch]

Help!

I am paranoid about safety ever since I almost died in an accident.
Have already put an addco rear sway bar on my
1972 GMC Jimmy 4x4 w/leaf springs

But the Addco front sway bar that was supposed to work does not work on a 4x4 like Addco listed it did. Talked to Addco direct, they now agree and had me return it. Probably just designed for a RWD, not a 4x4

Hellweg had one, their 7431, that would have worked but they have discontinued it.

Has anyone put a front sway bar on a 69-72 4x4 ?
If so, from what company and part number?
Has anyone put a sway bar on a 69-72 from a later model c/k series?
Or from another truck?
Any modifications needed?

Would appreciate any help I can get.
