77 pinto instrument cluster
« on: June 26, 2020, 06:54:33 PM »
Can a 1975-76 Pinto instrument cluster be reworked to be placed in a 1977 Pinto?

The printed circuit for each year has a different color. The circuit for 76 and some 77 is pink. The difference from year to year is the amount of wiring. As years advanced, the wiring grows and the plug gets bigger.  I know that a 75 had less wiring therefore a smaller plug. That is why I needed to keep the printed circuit from my 76 to put on the 77 cluster. If you use 75 or earlier year, keep your printed circuit but you will need to cut larger hole in the white plastic to fit the larger wiring plug.
There were three 76 clusters in the Colorado junkyard and all were crumbs. Yes a 76 will fit the 77 if you find one that is in good shape. The key will be to match the printed circuit color to you current car. I assume you can use other years cluster with a major rewire.

This question brings up another. IF..., one has a decent cluster housing is there anything that can be sprayed over it (Urethane etc.) to slow or stop the deterioration? It would be interesting to know why the clusters deteriorate but the "science of plastic" eludes me.  https://youtu.be/eaCHH5D74Fs?t=26
