Request for 68 Panhard Bar/Track Bar dimensions

[NC1968Riviera]

I am thinking about having a new adjustable length panhard bar (track bar) built for my 68. Does anyone have the center to center of the bushing length measurement and the dimensions of the bushings? Are they the same as first gen Rivs? I can go look at my car at my mechanics tomorrow but I am hoping someone already has the information so I can pass it along to the part builder. Apparent this guy specializes in building 63-65 panhard/track bars and has a good reputation . 

Any help with the stock dimensions would be greatly appreciated!
