Wilton 303 Pow-R-Arm / Garfield H1-A-1 RE-assembly HELP!!!

I recently found an OLD Garfield H1-A-1 POW R ARM, the same as a Wilton 303 Pow-R-Arm (I believe Wilton bought the patent from Garfield) and when I took it apart (it was siezed) the two rubber "plugs" that hold the hydraulic fluid int the resevoir popped out before I could see their original position... All of the parts are cleaned and in great shape, I just don't know the first thing about this unit and want to get it right! Any help would be appreciated!

Did you try Wilton? Years ago I was rebuilding my lever type PowerArm and Wilton faxed me a drawing of the parts that I needed.
