Need Shocks Identified for Rebuild

[bk2life]

These are older 'air ride tech' shocks.
They are not listed on their site, no part numbers on the body.
2 Patents, and 2 different serial numbers.

I have bee told they are Vari-Shocks; but i would like to confirm this.

There is some leakage at the adjustment knobs and I'd like to have these broke down and rebuilt.

Other than age, these are in great shape, and should be zero wrong with rebuilding them.

Any help greatly appreciated.
