[QUOTE=whunter;2827863]If you have a link, I need to review that shock absorber documentation.
It can not apply to GAS charged STRUTS.

Again It looks like Hunter is right. If the gas component pressure retention is lost. The shock manufacturer may have meant a very small weepage does not mean the gas charge is lost. Shaft seal has to get a small amount of lubrication or be a self lubricating type of plastic perhaps.
With no gas charge left in a shock I again suspect the car would bottom out the front end too easily. Even back in the early sixties these cars where sensitive to shocks more so than the average car. My fintails probably had gas blistein shocks even back then. I knew they were blisteins for sure but if gas or not I cannot say absolutly for sure. Other than knowing when they were bad they were really bad.
