          | Where can I find under carriage wear specs HD5?   My track chain rail height is about 3.5 inch.  How close to new is that? 
 Thanks
 Shawn

          | I printed the photo and enlarged it close to proper scale. 
 Looks like around 3 5/8 in. New rail height.
 
 Recondition at 3 3/8 in. Rail height.

          | the picture is one i posted a few years back of one of the track gauges I have Unsure if anyone makes them now , I have one in Aluminum and other in plastic .
 Friend junked out a old salvage yard here in MN and i got several track gauges from him , kind of nostalgia items - when I sell my HD5G (if ever) might part with the extras but for now will just hang in shop .

          | Cool. Thanks for posting that photo.  Does my estimate match up with your gauge? 
 I saw an aluminum Cat D4 years ago.  I bought a reproduction 20 years ago

          | It's why I posted it with the ruler as it seems the copy I first made was not to scale but figured the ruler would allow someone to size it accordingly

 Any chance of getting a photo of that gauge lying on a piece of graph paper? That would make it really nice to duplicate to scale
