brake rod swap for power booster?

[steverino66]

I'm stuck - putting an 83 brake power booster in my 66, looks like I need to use the '66 rod to get enough length for pedal travel. (The 66 rod is adjustable for length). I have the 83 booster apart, but can't figure out how to get the small barrel-shaped end with the spring underneath off the end of the 83 rod. And will the 66 rod attach properly if I do get the 83 apart?
I know a pic would be helpful here, but no digital camera available right now. Any help appreciated. Anyone have a clue?
