Now I went and did it. Tried to take out the tach and speedo hsg.gauge cluster to check on some wiring and dash lites that don't work. That plastic housing is as fragile as an eggshell and the top portion of it just fell apart. From what I have read on this issue, there isn't any replacements for these housings. So now I am trying to superglue this thing back together. With pieces of gauge cluster housing from the 86 Ranger I'm boning out I am making some headway. Have to go buy more glue and when I have it where I want it, coat it with something bullet proof to help keep it together. If someone out there has a good one, or an idea of what might fit in place. From what I've gathered my 77 Pinto Wagon has the Rally gauges with the tach and speedo behind steering wheel and 3 gauges in center of dash above console.
Thanks.
