Autometer 2894/2895 tach install for 63-65 clusters!

I credit Travis Newhouse with the information provided here.  He was kind enough to give me a quick rundown on how to do the install.  The pictures displayed here are from the installation of the tach in my instrument cluster.  NOTE: Other model tachometers will fit, they must be external mount type and have a diameter of 3 3/4", but may interfere with the inner dash brace.  If done correctly, the Autometer 2894/2895 tach will not interfere with this dash brace!


Step 1.) Remove external mount base and steel strap. Retain steel strap and discard base.
When finished, it should resemble the picture.

        Step 2.) Remove outer glass retaining bezel by gently prying up the edges NOTE: This will permanently blemish the tach, 
          and it will no longer be suitable for external mount.  Remove glass insert.




        Step 3.) Remove 3 mounting nuts on the rear of the tach mounting cup.  Carefully remove the the tach assembly from
          the cup, pulling the complete harness through the rear grommet.




        Step 4.) Turn cluster over.  Remove center insert or clock by removing 2 screws, pull center out




        Step 5.) Insert tachometer assembly back into mounting cup. Insert cup and tachometer assembly in cluster center from 
          the rear as show in picture.  Lift instrument cluster above your head and turn tach to desired position.  Note postition of   
          of mounting cup on rear of cluster.  Now remove mounting cup, pull tach assembly out of cup and reinsert cup in
          cluster noting the before position.  Use Steel strap removed in Step 1 to fashion mounts.  The best way to secure the
          mounts is to mount them to the cluster utilizing the 2 screws removed in Step 4, in the same location you removed them


        Step 6.)  As you can see, I chose to drill a hole through the center of the cup. Although this method will work well, I
          suggest you secure the mounts to the side of the cup and not the top.  If the screw in the center of the cup is too long,
          it may interfere with the inner dash brace.  I initially had this problem, but trimmed the screw down and it fit snugly.
          After you design and secure your mounts, install the tach assembly back into the mounting cup and secure the whole
          assembly to the cluster.  TIP:  If you are not satisfied with the fit around the edges of the cluster, look inside the tach
          bezel that you removed in Step 1, you will find some foam, use that to fill the space around the mounting cup. 


        Step 7.) Your finished product should look similar to the picture!





        Step 8.(optional). If you are concerned about "Hard Wiring" the tach in, pick up a standard 4 pin connector at your local 
          electronics store.  This will create a quick disconnect in case you need to remove the cluster at a later date!
